Abstract:
AC Servomotors are widely used in the industries for the control of static and dynamic loads. Precise control of position, speed, and torque are the main issues with the AC Servomotor. AC Servomotors are highly demanded by the industries to have a precise response under dynamic load conditions. Many control techniques are commercially available for the control of AC Servomotor under static and dynamic load conditions. However, all of these control techniques have advantages and limitations. Many investigations are done on the control of AC Servomotor, but comprehensive surveys on the control of AC Servomotor were still limited. In this paper, most of such commercially available control techniques are investigated, discussed, and compared.

Abstract:
The paper presents works carried out by the authors in the field of NC axes’ structural and functional optimization. This paper includes the results obtained by using a MathCAD application (developed in the doctoral thesis of the second author) for the servomotor's thermal behavior computer assisted evaluation. The analyzed servomotor is included in the driving system of a linear motion NC axis experimental testing stand, (existing in MMS department from EMTS Faculty). The NC axis of the experimental stand integrates a FAGOR brushless servomotor, a 1:1 ratio belt drive intermediary transmission, a ball screw - bearings assembly (lead screw - ball nut - bearings) and a driven element guided through a ball rail system. The MathCAD application was developed in order to perform specific calculation for servomotor's thermal energy dissipation and maximum operating temperature evaluation, and allows to perform the assisted final check and optimum selection of the electrical driving servomotors based on these results. The paper presents, through some screenshots from running the MathCAD application, the computer assisted evaluation procedure and results of the brushless servomotor's thermal behavior analysis corresponding to analyzed NC axis (included in the experimental stand).

Abstract:
In steam turbine control and actuation, the steam control valve plays a key role in operability and reliability. The electrohydraulic regulating system for the steam control valve, usually called the servomotor, needs to be reliable and high performing under nonlinear excitation interference in actual conditions. Currently, electrohydraulic servo valve control technology is widely used in servomotors. Although this technology has good control performance, it still has some technical defects, such as poor antipollution ability, low energy efficiency, large volume size, and limited installation space. Aiming at the abovementioned technical shortcomings of electrohydraulic servo valve control technology, a servomotor-pump-hydraulic cylinder volume control scheme is proposed in this paper, forming a pump-controlled servomotor for the steam control valve. By analyzing the working principle of the pump-controlled servomotor position control in the steam control valve, the mathematical model of a pump-controlled servomotor for the steam control valve is established. The sliding mode variable structure control strategy is proposed, and the variable structure control law is solved by constructing a switching function. To verify the performance of the proposed control method, experimental research was conducted. The research results show that the proposed sliding mode variable structure control strategy has a good control effect, which lays the theoretical and technical foundation for the engineering application and promotion of pump-controlled servomotors for steam control valves and helps the technical upgrade and product optimization of steam turbines.

Resumo Este trabalho teve por objetivo o estudo de ligas sinterizadas a partir de Fe puro, FeP, FeSi e FeNi obtidas a partir do processo da Metalurgia do Pó e sua aplicação em núcleos de rotor e estator de servomotores, operando com corrente elétrica de armadura de alta freqüência, reduzindo assim, nestas frequências, as correntes parasitas, as quais causam perda de potência nestas máquinas. O estudo compreendeu obtenção de curvas de histerese destas diversas ligas, ensaios para avaliação de perdas elétricas e simulação em software de elementos finitos para obtenção de fluxo de entreferro e conjugado eletromagnético (torque). Os estudos teóricos e simulações foram realizados em um servomotor de topologia convencional e os testes foram realizados comparativamente a servomotores com núcleos obtidos a partir de chapas de aço laminadas. Nas simulações realizadas estaticamente, o torque instantâneo e o fluxo magnético no núcleo de Fe1%P resultaram valores próximos em relação às tradicionais chapas de aço laminadas. O núcleo de Fe1%P apresentou torque instantâneo de 1,59 N.m e fluxo magnético de 1,70 T e o núcleo de chapas de aço laminadas, respectivamente, 1,65 N.m e 1,66 T.Palavras-chave: Metalurgia do Pó.

ABSTRACT This work aimed to study sintered alloys from pure Fe, FeP, FeSi and FeNi obtained by Powder Metallurgy process, and its application in rotor and stator cores of servomotors, operating with armature electric current in high frequency, thus reducing, in these frequencies, eddy currents, which cause loss of power in these machines. The study comprised obtaining hysteresis curves from these different alloys, tests to evaluate electrical losses and simulation in finite element software to obtain airflow and electromagnetic conjugate (torque). Theoretical studies and simulations were performed on a conventional topology of servomotor, and the tests were carried out comparatively to servomotors with cores obtained from rolled steel sheets. In the simulations performed statically, the instantaneous torque and the magnetic flux in the Fe1%P core resulted close values in relation to the traditional laminated steel sheets. The Fe1%P core had an instantaneous torque of 1.59 N.m and a magnetic flux of 1.70 T and the core of rolled steel sheets, respectively, 1.65 N.m and 1.66 T.Keywords: Powder Metallurgy. Servomotors.

Abstract:
This paper presents the works carried out by the authors in the field of structural and functional optimization of industrial robot's numerically controlled (NC) axes. The study includes the results obtained in the research stage of the experimental measurements performed to evaluate the electrical servomotor's thermal behavior using a thermal (infrared) imaging camera. The analyzed servomotor is a brushless servomotor integrated in an experimental stand for linear motion NC axis experimental research, existing in the MMS department from EMTS faculty. Supplementary to the driving servomotor, the experimental stand includes a belt drive transmission, a ball screw - bearings assembly and a driven element guided by ball rail system. This experimental research phase is part of the doctoral thesis of first author and was conducted in order to validate the mathematical models developed in the PhD thesis. Thus, experimental results presented in the paper have been used to validate first mathematical models for electric motor's preliminary selection and checking, (performed by determining the total reflected inertia of the mechanical system on motor shaft level) as well as the mathematical models for final selection and checking (by evaluating the servomotor's thermal energy dissipation, and servomotor's internal and external maximum operating temperature). Second, the experimental results have been used to validate the assisted simulation for structural and functional optimization of industrial robot's NC axes based on both servomotor and drive's thermal behavior analysis, performed in the thesis by means of a dedicated commercial software package.

Abstract:
Robotic tasks often exceed the scope of steady-state or periodic behavior, which necessitates generally-applicable models of actuators intended to generate transient or aperiodic motion. However, existing electromechanical models of servomotors typically omit consideration of the switching power converter circuits required for directional, speed, or torque control. In this study, a multi-domain framework is established for switched electromechanical dynamics in servomotor systems for their analysis and control in general aperiodic tasks including transient phases. The switched electromechanical dynamics is derived from the individual models of the internal DC motor, gear train, and H-bridge circuit. The coupled models comprehensively integrate all possible distinct switching configurations of on-state, off-state, and dead time. A combination of cycle averaging with piecewise analytical solutions of the non-smooth dynamics is introduced to handle different temporal scales from high-frequency electrical to low-frequency mechanical variables. System parameters were estimated from experimental data using a dual-servomotor test platform. The model was validated for predictive accuracy against measured data in two distinct tasks—dynamic braking of a pendulum system and sinusoidal trajectory following. The model was also used to formulate the servomotor power consumption, which was implemented for optimal control demonstration and energy analysis. In particular, the servomotor power consumption model provided true optimality (minimization) when compared with the squared rotor torque and the positive rotor mechanical power that are commonly used as proxy models. While the focus of this work is on permanent-magnet, armature-controlled brushed DC servomotors, the approach is applicable to general electromechanical systems with switching-based control.

Abstract:
This paper proposes a novel concept of active balancer for reducing the input torque fluctuations of mechanisms. A differential gear train is used in this active balancer and one of its two input shafts is driven and controlled by a servomotor. From the structural point of view, it is designed as an independent device that can be assembled and disassembled easily; from the functional point of view, it can minimize the torque fluctuations in a variety of working conditions. At first, an exact control function of the servomotor that can totally eliminate the input torque fluctuations of the mechanism is gained by an analytical method; in what follows, an optimization approach is developed to select appropriate control functions for the servomotor to balance the input torque of the working mechanism with consideration of the servomotor’s own input torque minimization; finally, an integrated method is presented for optimizing both the control function of the servomotor and the structure parameters of the differential gear train. Two numerical examples are given to illustrate the design procedure and to show its feasibility.

Abstract The authors consider the features and operation specifics of the synchronous permanent magnet motors and the synchronous reluctance motors with electronic commutation in servomotor operation modes. Calculation results show that mechanical and control characteristics of studied motors are close to a linear shape. The studied motor control is proposed to implement similar to phase control of induction servomotor; it means that angle θ (angle between vectors of the supply voltage and non-load electromotive force) or angle ε (angle between rotor direct axis and armature magnetomotive force axis) is changed. The analysis results show that synchronous electronically commutated motors could be used as servomotors.

Abstract:
The vBow, a virtual violin bow musical controller, has been designed to provide the computer musician with most of the gestural freedom of a bow on a violin string. Four cable and servomotor systems allow for four degrees of freedom, including the lateral motion of a bow stroke across a string, the rotational motion of a bow crossing strings, the vertical motion of a bow approaching and pushing into a string, and the longitudinal motion of a bow travelling along the length of a string. Encoders, attached to the shaft of the servomotors, sense the gesture of the performer, through the rotation of the servomotor shafts, turned by the motion of the cables. The data from each encoder is mapped to a parameter in synthesis software of a bowed-string physical model. The software also sends control voltages to the servomotors, engaging them and the cables attached to them with a haptic feedback simulation of friction, vibration, detents and elasticity.

Abstract:

In this bachelor thesis, diagnostic methods for one of Siemens stem inlet control valves have been developed. The work has taken place during ten weeks at Siemens Industrial Turbomachinery AB in Finspång. The company produce steam- and gas turbines and also provides service and maintenance.

 

The purpose with this project has been to develop diagnostic methods that oversee the health of the control valves. By using the developed methods you will know when it’s time for maintenance. With these diagnostic methods it’s possible to some degree leave the predetermined maintenance that Siemens uses today on their control valves.

 

The project has been limited to involve just one of Siemens control valves. The report describes the control valve’s function and the components included in the valve structure. It describes the problems that can occur with the valve and what could be done monitoring it to detect potential failures before they develop into functional failures.

 

A short description of different measuring equipment and how they work is also included.

 

Interviews have been conducted at Siemens, at Linköpings University and also with companies that delivers measuring devises. A visit to follow a vibration measurement of a control valve at Idbäcksverket in Nyköping has also taken place. Another tool that has been used in this work is an FMECA that describes errors that may occur with the control valve and what caused them. Books and the internet have also provided necessary facts.

 

This report presents some recommendations on what to do to monitor health of the control valve and equipment to prevent functional failures. The intention with the report has been to show that the equipment presented here can be used in the future to avoid unnecessary preventive maintenance and eliminate the use of corrective maintenance.

This work presents a study about non-continuous sliding modes control applied to Permanent Magnetic AC motor (PMAC), also called AC Servomotor. The two main objectives of this work are: to analise the robustness of the technique related to load disturbance and variations in the windings resistance; and to study alternative ways to reduce chattering. The first part includes a study about the modeling of conventional synchronous motors and PMAC motors, both with salient poles. The aim is to study the models used in the movement control of the referred motors in the synchronous reference frame. The second part presents a study about first order sliding modes control, including a method of high frequency switching (chattering)minimization. Simulation results are presented that confirm the efficiency of the techniques applied. Finally, in the third part we study higher order sliding modes control, aiming at chattering minimization. The concepts developed are those for a 2nd order control. Again, simulation results are presented that confirm the efficiency of the techniques applied.

Abstract:
På KTH-Södertälje finns laborationsutrustning som inte har använts på länge. Utrustningen som behandlats i detta examensarbete är ett antal servobord. Ett servobord har en servomotor som roterar en cirkulär platta. Plattan är försedd med vita fält och en visare, och på utsidan av plattans omkrets finns markörer för olika vinklar. Detta tillåter att motorns vridningsvinkel går att avläsa. De vita fälten på plattan kan avläsas med optiska sensorer och möjliggör att motorn kan styras med hjälp av pulser. Motorn på servobordet är även sammanlänkad med en potentiometer. Potentiometern tillåter att spänningsnivåer, som står i relation till motorns vridningsvinkel, kan utläsas. Ett önskemål fanns om att denna utrustning ska kunna används i en laboration. Målet meddetta arbete är att programmera system för styrning av motorn till en önskad position. Därefter ska dessa system kunna ligga till grund för en laboration. De olika positionerna som motorn önskas styras till betraktades som våningsplan i ett hissystem. Visaren på den cirkulära plattan betraktades som en hisskorg. I LabVIEW skapades det användargränssnitt som tillåter att en användare bestämmer vilket våningsplan hissen ska åka till. För att skapa laborationen var nästa steg i arbetet att ta bort delar av programmeringen för att låta studenterna komplettera programkoden. Slutligen skrevs en laborationsinstruktion.
At KTH Södertälje there is laboratory equipment that has not been used for a long time. The equipment that was used in this project is several servo boards. A servo board is equipped with a servo motor that rotates a circular plate that has white fields and a pointer, and on the outside of the plate´s perimeter there are markings that indicate different angles. This allows reading of the motor´s angular position. The white fields on the plate can be detected by optical sensors and enables the use of pulses to control the motor. The motoron the servo board is also connected to a potentiometer. The potentiometer allows reading of the voltage that correlates to the angular position of the motor. A request was made about using this equipment in a laboratory exercise. The objective of this project is to program a system to allow control of the motor to a desired position. These systems will then be the basis of a laboratory exercise. The different desired positions of the motor were regarded as floors in an elevator system. The pointer on the circular plate was regarded as the elevator cage. A user interface was created in LabVIEW that allows a user to decide which floor the elevator should go to. To make the laboratory exercise, the next step was to remove parts of the program that the students then must complete. The last part of the project was to write an instruction for the laboratory exercise.

Abstract:

Examensarbetet har genomförts på Siemens Industrial Turbomachinery AB i Finspång. Arbetet innebär modernisering av ventiler till ångturbiner. Uppgiften består av två delar, där den första delen är att modernisera dagens tätningar i spindelgenomföringen. Syftet är att finna en mer vibrationstålig, driftsäker och mindre utrymmeskrävande lösning. Det andra delprojektet är att finna alternativ till dagens tallriksfjädrar i de servomotorer som reglerar ventilen. Anledningen till att nya fjädrar skall tas fram är att öka livslängden, minska slitaget och utrymmesbehovet på servomotorerna.

För att kunna genomföra uppgiften på ett effektivt och strukturerat sätt har en metodik för systematisk konceptutvecklings används. Denna metodik har varit hjälpfull för att finna nytänkande lösningar. För att kunna dimensionera komponenterna har beräkningsmodeller tagits fram för de ångkrafter som verkar i en ångventil samt för olika typer av packboxar och fjädrar.

Arbetet med moderniseringen av spindeltätningar har resulterat i att en ny typ av packbox har valts som minskar friktionen samt behovet av efterdragning. Två olika lösningar har tagits fram för att skapa den förspänningskraft som gör att packningen tätar. Båda lösningar minskar behovet av underhållsarbete samt underlättar monteringen. En indikation ges även när rätt kraft är uppnådd, vilket minimerar risken för läckage eller att ventilen inte går att manövrera.

Analysen av servomotorer resulterade i att inga möjliga alternativ till tallriksfjädrar hittades. Modifieringar har därför tagits fram för att förbättra dagens tallriksfjädrar. Dessa ändringar innebär att slitaget minskas och livslängden ökas betydligt.


This thesis was preformed at Siemens Industrial Turbomachinery AB in Finspång. The work is to make modernizations of steam turbine valves. The first part of the project is to modernize stem packing with the purpose to find a more reliable and space-saving solution that is less sensitive to vibrations. The second part is to find an alternative solution for cup springs in servomotors. A new spring type is desirable to increase the lifetime, lower the wear on stem shafts and to make it more space-saving.

To be able to perform the task efficiently and organized a method for systematic design has been used. This method has turned out to be quite useful tool in order to find new approaches to problems. Calculations of steam forces in a valve together with different types of box packing and springs have been done.

The modernization of stem packing has resulted in a new type of box packing. The winnings of changing packing are lowered friction and need of maintenance. Two solutions of live load systems have been created. Both solutions minimize the need of maintenance and make the mount and dismount easier. An indication makes sure that a sufficient force is applied on the box packing.

An analysis shows no alternative to replace the existing cup springs. The main goal was changed and modifications were made to improve the cup springs. The modifications results in a lowered wear and a significant increase of cup spring lifetime.

Gripdon är vanliga i många branscher. De kan exempelvis lyfta och transportera föremål såsom lådor och bilar. Gripdon kan hittas i olika storlekar, tillräckligt stora för att transportera en bil eller tillräckligt små för att sortera även piller. Normalt är gripdon anpassade till en specifik uppgift. Gripdonets form är beroende av föremålet som det ska hantera. Normalt är föremålet enhetligt i form och vikt. Utmaningen här är att projekts gripdon ska kunna hantera föremål av olika storlekar och vikter. Gripdonet som utvecklades för detta projekt kommer att transportera föremål som väger någonstans från 3 kg till 28 kg. Det erforderliga omfånget av dimensioner är som följer: höjd 200–600 mm, djup 300–1 000 mm och längd 300–1 000 mm. Förutom de olika storlekarna krävdes även att gripdonet ska förflytta föremål med tillfredställande hastighet. Initialt skulle griparen vara fäst vid manipulatorn ABB IRB 4600. Denna modell kan transportera upp till 40 kg, därför borde det utvecklade gripdonet ha en viktgräns på 12 kg. Många olika lösningar studerades för att hantera utmaningen. Den valda lösningen baserades på att ha två linjära enheter drivna av servomotorer. De linjära enheterna är synkroniserade och rör sig i motsatta riktningar. Det finns linjära enheter som möjliggör synkroniserad motsatt rörelse men de tillgängliga modellerna skulle avsevärt sakta ned och skulle inte vara väsentligt olika i vikt eller pris jämfört med den konstruerade enheten. Griparens konstruktion är baserad på det maximala kontaktområdet med lådan för att öka friktionen mellan gripdon och kartongen. Griparens form är utformad för att undvika att deformera metallen och att gripdonet inte behövs repareras under lång tid. Konstruktionens kanter är konstruerade med plåtfästen för att försäkra att gripdonet inte böjer sig. Griparens uppskattade vikt är betydligt högre än de ursprungliga förväntningarna. Därför skulle IRB 4600, 40 kg manipulatorn behöva ersättas av en modell som kan bära den uppskattade vikten (cirka 250 kg=).
Gripers are common in many industries; they can lift and transport a variety of objects such as boxes and cars, for example. Gripers can be found in a full spectrum of sizes; large enough to transport a car or small enough to sort the smallest of pills. Grippers are typically customized for a specific task; the shape of the griper is dependent on the object it will carry. Normally, the object is uniform in its shape and weight. This project required the griper to handle multiple objects of various sizes and weights, presenting a particular challenge. The griper that was developed for this project will transport objects weighing anywhere from 3 to 28 kg. The required range of dimensions are as follows; height from 200 to 600 mm, depth of 300 to 1000 mm, and length from 300 to 1000 mm. In addition to the variety of sizes, the griper was also required to move objects with speed. Initially, the griper would be attached to the manipulator ABB IRB 4600. This model can transport up to 40 kg, therefore the developed griper should have a weight limit of 12 kg. Many different solutions were studied in order to solve the challenge of multiple size and weight variations. The chosen solution was based on having two linear units driven by servo motors. The linear units are synchronized and move in opposite directions. There are linear units that allow for synchronized, opposed movement but the models available would significantly slow the movement and would not be materially different in weight or price compared to the designed unit. The design of the griper is based on allowing the maximum contact area with the box to increase friction between the gripper and cardboard. The shape of the griper is designed to avoid deforming the metal and ensuring the griper will not need to have it's parts repaired for a long time. The edges of the structure are constructed with bent sheet metal brackets, to assure the griper will not bend. The estimated weight of the griper is significantly heavier than the original expectations. Consequently, the IRB 4600,40 kg manipulator would need to be replaced with a model that can carry the estimated weight of approximately 250 kg.

Abstract:
Hybrid actuation robotic systems are mechanical systems that contain both servomotors and constant-velocity (CV) motors. Due to this nature of hybrid actuation, design of hybrid actuation robots is governed by both mechanism and robot design theories and methodologies. For instance, the path generation problem in mechanism design may take advantage of the effect of the servomotor for its real-time adjusting function, for which inverse kinematics needs to be established on the servomotor. In this paper, we first generalize four types of path design problems. We then present a general formulation of inverse kinematics for a five-bar hybrid actuation robot and compare two specific approaches to inverse kinematics in the literature in terms of of their computation and suitability to the path design of hybrid actuation robots. Finally, we extend the result for the five-bar hybrid actuation robot to a general hybrid actuation robot.
