Full textThis report presents the work carried out aiming towardsdistributed control of electric drives through a networkcommunication medium with temporal constraints, i.e, Ethernet.A general analysis on time delayed systems is carried out,using state space representation of systems in the discretetime domain. The effect of input time delays is identified andis used in the preceding controller designs. The main hardwareapplication focused in this study is a Brushless DC servomotor, whose speed control loop is closed via a 10 MbpsSwitched Ethernet network. The speed control loop, which isapproximately a decade slower than the current control loop, isopened and interfaced to the network at the sensor/actuatornode. It is closed at the speed controller end at another nodein the same local area network (LAN) forming a distributedcontrol system (DCS).
The Proportional Integral (PI) classical controller designtechnique with ample changes in parameter tuning suitable fortime delayed systems is used. Then the standard Smith Predictoris tested, modified with the algebraic design techniqueCoefficient Diagram Method (CDM), which increases the systemdegrees of freedom. Constant control delay is assumed in thelatter designs despite the slight stochastic nature in thetiming data observations. Hence the poor transient performanceof the system is the price for the robustness inherited to thespeed controllers at the design stage. The controllability andobservability of the DCS may be lost, depending on the range inwhich the control delay is varying. However a state feedbackcontroller deploying on-line delay data, obtained by means ofsynchronizing the sensor node and controller node systemclocks, results in an effective compensation scheme for thenetwork induced delays. Hence the full state feedbackcontroller makes he distributed system transient performanceacceptable for servo applications with the help of poleplacement controller design.
Further, speed synchronizing controllers have been designedsuch that a speed fluctuation caused by a mechanical loadtorque disturbance on one motor is followed effectively by anyother specified motor in the distributed control network with aminimum tracking or synchronizing error. This type ofperformance is often demanded in many industrial applicationssuch as printing, paper, bagging, pick and place and materialcutting.

Full textThis work proposes a low-cost hybrid hardware and software system that, through a set of methods and nested while loop fitting algorithms, allows to automatically identify the electrical and mechanical parameters of a brushed direct current motor. The aim is to facilitate a tool that contributes to the development of motion control projects in which this type of actuator is used, automating and speeding up the identification process of the motor system aiming to reach 98% accuracy, in order to guarantee a good electrical and mechanical parameter estimates for the brushed direct current motor. To achieve the objective, a platform was developed consisting of a main interface programmed in Matlab and a data acquisition hardware based on a single-phase incremental optical encoder, an H-bridge, an optocoupler circuit, and a C language-programmed DSPIC30F2010. Both parts of the platform are interconnected through the authors' own serial communication protocol.

Full textIn this thesis, the theory behind a separate-winding excitation direct current (DC) motor and profile of the motor's torque versus rotor speed is studied. The torque versus rotor speed profile results are predictably linear at a given armature voltage. Output torque of a separate-winding excitation DC motor is proportional to the armature current. From this theory, a program was written in Simulink with Xilinx embedded software to enable a user to command the DC motor torque through a Graphical User Interface (GUI). The command is then converted to control armature current through a Field Programmable Gate Array (FPGA) to the DC motor. The armature current level is maintained through a programmed Proportional Integral (PI) Controller to keep output torque constant regardless of armature voltage and rotor speed. This result is a way to command constant output torque to a DC motor.

The purpose of this thesis is to realize an entire digital PC-Based Linear direct current brushless servo motor system. In hardware, we utilize the motor coprocessor chip and Application Specific Intelligent Power Module (ASIPM) with peripheral circuits design to build a motor driver module. And use personal-computer as a controller to deal with the calculation of control rules and transmits the real-time commands to achieve the purpose of software servo control. In experimentation, we use a different way from rotary DCBM to measure linear DC brushless motor parameters. And we adopt sinusoid pulse width modulation method by voltage-fed inverter to drive motor. By the use of V/F control and vector control, we make experiments about position and velocity closed-loop on the single-sided linear direct current brushless motor to prove the hardware and control schemes are available.

Several adaptive impedance controllers are proposed in this thesis based on the function approximation technique for a DC servo motor interacting with the environment. Stable compliant motion can be achieved without the need for the force feedback in the new strategy. Uncertainties in the plant parameters can also be tolerated. The closed loop stability is proved by using the Lyapunov-like technique. Experimental studies justify the feasibility of the proposed controllers.

This thesis aims at proposing two adaptive motion control methods with radial- basis-function neural network (RBF NN) for a linear DC brushless motor, and one adaptive control method for an inverted pendulum mounted on the linear motor. A simplified model of a linear motor with a current driver is adopted herein. Based on some upper bound assumptions of the motor ripple force and the nonlinear friction force, an adaptive RBF NN control is proposed to achieve velocity tracking control. With the same control concept, an adaptive backstepping RBF NN control is presented to achieve position tracking. Moreover, the adaptive backstepping RBF NN control approach is also utilized to regulate the inverted pendulum mounted on the linear motor. Computer simulation and experimental results are conducted to show the feasibility and effectiveness of the proposed control schemes for velocity tracking, position tracking and inverted pendulum control.

As the human’s heart, motor in mechanical system provides power source for running the equipments, so the motor performances such as the responding speed and the stability are very important. In daily life, the applications of DC motors such as rolling doors, pump motors, are able to operate while beyond the static friction force. In the process it will encounter in magnetic saturation as well as the long stable time that causes the system out of control. Therefore nonlinear research has gradually attracted people’s attentions. In this study, firstly, Matlab Simulink software was applied to construct the system control model for stability analysis. Secondly, Routh–Hurwitz(R-H) stability criterion and describe function method are used to obtain the stability parameters of controller. By using PID controller, a verification result of subsequent system shows that the response curve of R-H criterion is not acceptable. On the other hand, for better, the description of system stability by DFM demonstrates that the system can still return to the stable state under external disturbance influence.

Due to the advanced progressivism, performance rising and cost down of Personal Computers (PC), the PC based control has become the hot research topic. At the same time, the PC based control has been the main trend in industrial control because it can achieve the fast data process, network, friendly human machine interface and etc. Many control theories have been developed for several years. From these methods, the PID control is one of the most extensively used methods in the industrial controls, since the calculation of PID control is very simple and easy to realize. After tuning the necessary parameters, one can get a good control performance. By integrating of PC and PID control rule, a DC servo motor position control is implemented through the printer port. The effects of controller parameters are also discussed in this thesis according to experimental results.

In recent years, green policies have been continuously implemented for achieve sustainable development, and one of the biggest reasons is the energy issue. It is harmful to our living environment whether from the use of the oil, electricity to the nuclear energy. To solve the energy problem is nothing more than developing green energy or starting from energy saving. Among them, direct current motors (DC motors) play an indispensable role in future trends. DC motors can be used for using service robots, aircrafts, scooters, etc. and therefore they have a vital position. At the current stage, DC motors are basically divided into brushed DC motors and brushless DC motors (BLDC motors). However, brushed DC motors have gradually not been used because their power consumption and structural problems are hard to be improved. Most of the BLDC motors are controlled by the basis of Hall sensors, but the BLDC motors loaded with Hall sensors have higher cost and lower environmental adaptability. Therefore, the sensorless BLDC motors controlled by the basis of motor back electromotive force (back EMF) are derived from the former. The measurement of back EMF usually requires the use of a filter circuit and a comparison circuit. While the microprocessor clock is gradually accelerating and the functions are gradually being integrated, the microprocessor can integrate the measuring circuit of the back EMF, thereby reducing the circuit cost and the risk. This paper will use HT32F52352 to collect all the back-EMF circuits, and adjust the speed, torque compensation, blocked rotor test and status display. We will compare various control methods to propose the most suitable method for microprocessor-controlled sensorless BLDC motors.

This paper presents a remotely fuzzy control in DC motor speed monitoring system with LabVIEW and Matlab. We use fuzzy controller to adjust parameters, in order to get the optimal speed response. First, the membership functions are defined according to motor dynamic mode, and use Matlab to construct fuzzy controller. Using Fuzzy PID system and Linear Fuzzy Controller (training by Adaptive Network-base Fuzzy Inference System, ANFIS) respectively construct the controller of the monitoring system. The difference of the two controllers at the speed response is discussed to compare. Tracking of Fuzzy PID controller is faster, but there is still some steady error. Tracking of Linear Fuzzy Controller is slower, but output response is more correct. And designer don’t have to adjust gains or parameters of system in Linear Fuzzy Controller training by Adaptive Network-base Fuzzy Inference System. A friendly Man-Machine Interface (MMI) is provided to make the operation more convenient and easier to use. The proposed scheme simplifies the design procedure and complexity of the fuzzy controller. Otherwise, RS-232 is used as an interface of DC motor speed monitoring system.

This paper mainly introduces the application of DC motor and sensor on the self-propelled vehicle control. The development of a self-propelled vehicle with a single chip micro controller (Arduino UNO) is designed to shorten the travel time and achieve the goal of taking a complete map by using the vehicle body structure, drive control, ultrasonic, tracing sensor and servo motor. . The experimental design considerations will maximize the score of the completed task and complete the entire map in an automated manner. The design focuses on the lightweight of the self-propelled vehicle. Therefore, the DC motor is used as the power supply source for the self-propelled vehicle, and the IC is used. The L293D controls the forward and reverse rotation of the motor. Using the concept of the overall mechanism and the design of the car body, the parameters of the control motor are controlled by the control logic in the single-chip (Arduino UNO) to control the behavior of the self-propelled vehicle. In this study, the Taguchi method was used to optimize the factors affecting the average number of maternal groups and the maternal variation, and the results of the analysis developed an optimal design. The optimal level combination of controllable factors is obtained by fuzzy theory to obtain the optimal level of controllable factors for the two quality characteristics, such as the mean number of the parent group and the variance of the parent group. The correctness of the multi-objective parameters is verified by the double-reaction surface method. The experimental results are satifactory.

Abstract Since the switched reluctance motor(SRM) has high starting torque and high speed operation characteristics, it is good adaptation for industrial application. No thesis about position control of SRM was publicly discussed until today. The purpose of this paper implemented the position control of SRM. Two control strategy is proposed. The first, one of control strategy used total sliding mode control law(TSMC) which was designed same performance described by linear-quadratic(LQ) method. TSMC improve perturbation of position due to parameter variation and load disturbance. Secondly, this paper propose multi-segment sliding mode control (MSSMC) to solve a particular increment motion control problem specified by a trapezoidal velocity profile. Each segment of the multi-segment switch surfaces is designed to match the corresponding part. Finally, a digital signal processor(DSP)-base experiment SRM system is built to demonstrate all the proposed algorithms.

In this thesis, we study monitoring and control for abrushless direct current motor (BLDCM) using a modified genetic algorithm (MGA). The MGA has combined a simplegenetic algorithm that includes operations of reproduction,cross-over and mutation with techniques of gene-immigration,gene-extinction and elitist to become a more efficient methodfor parameter search. This MGA is used to identify the valuesof the system parameters of a BLDCM first. Then a controlleris designed for the BLDCM by using a feedback linearizationtechnique. Control parameters are also tuned by the MGA. Inthe closed-loop system operation, the MGA is further appliedautomatically to monitor the change of system parameters ofphase-resistance and maximum flux-linkage due to the changeof temperature and to adjust control parameters accordingly sothat required control performance can be maintained. Computersimulation demonstrates the effect and the feasibility of theproposed control method.

Comparing to the conventional DC motor and induction motor, the brushless DC motor (BLDCM) has superior merits, such as high torque, high performance, extensive working speed range, and without commutator and brush. BLDCM has been widely used in the industrial applications because of its cost and efficiency. Normally, Hall-effect sensor is used to detect the rotor position for commutation. However, the Hall sensor is low-resolution especially at low speeds and sensitive to the temperature. Therefore, the sensorless control scheme is considered in the thesis. In the thesis, the rotor position is estimated without employing current sensors and analog-to-digital converters (ADCs) at standstill and during motor running. The initial rotor sector is first detected by employing low-frequency and low-voltage injection instead of conventional high-frequency and high-voltage injection to improve the sector estimation. After start-up, the rotor angle is synchronously estimated with pulse-width modulation (PWM) frequency such that the number of estimation increased in the case of lower speed command. This will be more efficient in low speed control. In addition, a new method which can raise the signal frequency of hall sensor through a frequency-independent phase shifter (FIPS) is proposed in this thesis. It can improve the performance of the control system especially at low-speed region. Finally, the DSP TMS320F240 and FPGA EP2S60F672C3 are adopted in the system to verify the effectiveness.

The objective of this dissertation is to investigate the control techniques of Brushless DC Motor (BLDCM) and inverter. A sensorless control technique and a current ripple reduction technique for BLDCM drive are proposed. Moreover, a dead time elimination technique and a current reconstruction technique for inverter are also presented. The relationship between pulse width modulation signal and floating phase voltage of BLDCM are analyzed for the development of sensorless technique which requires neither position sensor nor filter. Therefore, it does not need any phase compensation and system parameter for wide range speed control. The experimental results confirm that the BLDCM can be operated stably by the proposed method while duty ratio varying from 5 % to 95 %. Moreover, the causes of commutation current ripple are analyzed and a current ripple reduction technique is proposed. Commutation torque ripple is improved by reducing commutation current ripple for BLDCM drive. The experimental results show that the lowest commutation current ripple can be reduced to 0.1 p.u. of its reference by the proposed method. A dead time elimination technique which reduces voltage loss and current distortion for inverter is also presented. At the same time, the concept of current averaging without feedback current signal is used to overcome the issue that the current polarity is difficult to judge at zero crossing point due to current ripple. The experimental results illustrate that the lowest Total Harmonic Disstortion of inverter current is reduced to 0.7 % using proposed method. Finally, a current reconstruction technique which only uses one current sensor to reconstruct three phase current signals is proposed. The proposed technique can not only spread the detection range for current sensing in vector space, but also decrease the common mode voltage which generated by inverter. Since only one current sensor is require for the proposed method, the cost can be reduced significantly. The experimental results demonstrate that three-phase current of inverter can be reconstructed by the proposed method while reference voltage vector varying from 1.15 p.u. to 0.103 p.u..

This article put effort on the brushless motor control by sinusoidal pulse width modulation (SPWM) technique. Due to the rapid development of microprocessor technique, the CPU speed is increasing and its price is going down, and an all digital motor control driver by integrated microprocessor chip become feasible. The DC motors are more popular in the past industry due to the easy controllability. But we can not avoid all these drawbacks such as brush abrasion, frequent maintenance and low efficiency when using DC motor. The recent performance improvement in microprocessor makes the complex control for brushless motor driver possible. With the advantages of no brush abrasion, less maintenance and high performance, brushless DC motors have replaced the position of traditional DC motor in the industry. Sinusoidal pulse-width modulation is a good motor control technique, but it is hard to implement by common microprocessor. The complex algorithm and program is not easy to be updated, and hard to achieve effective control. The report adopts a digital signal processing chip, named by TMS320-LF2407 from Texas Instrument, to easily implement sinusoidal pulse-width modulation technique by virtue of the internal multiplier hardware. Finally, the brushless motor driver can be implemented in a single chip.

This thesis proposes the drive design of a brushless DC motor (BLDC), employing an Arduino DUE as the core processor. In recent years, power electronics and permanent magnet materials technology have been mature, and the microcontroller functions have been increasingly powerful with low cost. Based on these advantages, the BLDC motors with low production cost will have more widespread industrial applications, and be popular in people's daily lives. Though Arduino boards are application-oriented, they are for general purposes, not aimed for real-time controller design for the BLDC motors. The Arduino instruction set is derived from the Atmel instruction set. Thus the Arduino instruction set is more complex, but readable at the expense of immediacy. To enhance the efficiency of the BLDC drive design, we should apply as many Atmel instructions as possible, instead of the Arduino instructions, in the programming design. From drive theory to circuit implementation, the thesis presents how to apply Arduino DUE to finish BLDC drive design . Moreover, the PI controller is applied to carry out motor speed control. Experimental results demonstrate the accuracy of the proposed design. Arduino has been popular for being an open-source electronics platform, but to date, there are few further industrial applications. We hope this thesis can promote more industrial applications using more Arduino chips in the near future.

This thesis presents a robust output tracking control design method for a linear brushless DC motor with modeling uncertainties. Two frequency-domain specifications directly related to the mixed sensitivity function and control energy consumption are imposed to ensure stability and performance robustness. With regard to time-domain specifications, rise time, maximum overshoot and steady state error of the step response are considered. A generalized two-parameter PID control framework is developed via genetic searching and evolutionary searching approaches to ensure the specifications imposed. The proposed design method is intuitive and practical that offers an effective way to implement simple but robust solutions covering a wide range of plant perturbation and, in addition, if provides excellent tracking performance without resorting to excessive control. A multiple objective controller design specifications directly related to the mixed / control are also imposed which directly related to the stability robustness and optimal control on the time and frequency domains. An advanced evolution strategy is developed to solve the constrained multi-objective problem; it is a global search algorithm thus avoids trapping into the local minimum. The new design paradigm offers a way to implement simple but robust solutions that covers a wide range of plant perturbations and provides excellent tracking performance. For the proposed design methods, complete simulation and experimental studies are performed to verify the performance and applicability of our proposed design.

The purpose of this thesis is to realize an entire digital PC-Based linear induction servo motor system. The PWM drive card of induction motor which is based on motor coprocessor chip-ADMC201 is designed and is used to generate pulse width modulation signal and deal with some feedback signal. The controller is a microcomputer which deals with the calculation of control laws and transmits the real-time commands to achieve the purpose of software servo control. We order the parameters tests of linear induction motor which differ from rotary one. We adopt sinusoid and voltage space vector pulse width modulation methods by voltage-fed inverter to drive motor. By the use of V/F control, we make experiments about position and velocity closed-loop on the single-sided linear induction motor to prove the hardware and control schemes are available.

In this thesis, a robust control structure for high-speed/high-accuracy motion control of two-dimensional stepping motor is designed. The overall control system consists of the following elements: a disturbance observer in the velocity loop, a PD feedback controller and a repetitive controller in the position loop and a ZPETC based feedforward controller. To attenuate disturbances and system uncertainties, a disturbance observer is utilized in the velocity loop. A PD controller is used in the position loop to construct an asymptotically stable system. However, the high-frequency cogging forces generated during the motion of the planar motor can not be rejected effectively by the disturbance observer. This causes a chattering phenomenon. Since cogging forces can be viewed periodic disturbances, a repetitive controller is designed in the position loop to enhance the performance of disturbance rejection. Then for the sake of the motion control of high-speed/high-accuracy positioning/tracking, a ZPETC is added to the closed-loop feedback control system. The disturbance observer in the velocity loop and the repetitive controller in the position loop maintain the system robustness to the external disturbances and model uncertainties, and the ZPECT feedforward controller significantly improves the tracking performance. Finally simulations are conducted to show the effectiveness of the robust control structures.
