Abstract:
This paper presents a new adaptive hysteresis band control approach used in direct torque control (DTC) of the induction motor (IM) drives with the switching tables for the generation of PWM signals. Constant Hysteresis Direct torque control (CHB-DTC) method used the torque and stator flux errors to generate the stator voltage reference and frequency vectors for controlling the three-phase induction motor. The CHB-DTC gives better torque transient performance but it has large steady state ripples. To reduce torque and stator current ripples in CHB-DTC controlled induction motor drives a new adaptive hysteresis band control (AHB) approach is proposed, where the hysteresis band is adapted in real time with the stator flux and torque errors variation, instead of fixed bandwidth. Both classical CHB-DTC method and the proposed adaptive hysteresis band DTC (AHB-DTC) fed three induction motor have been simulated using Matlab/Simulink. The simulation results at different operating conditions over a wide speed range demonstrate the validity, effectiveness, and feasibility of the proposed scheme. The measurements showed that torque ripples were significantly decrease with the new AHB-DTC technique and better speed response in step up or down compared to the CHB-DTC.

Abstract:
Direct torque control "DTC" technique is one of a high performance control system of an AC motor drive, which was proposed after the vector oriented control scheme during the resent 25 years. It has been developed rapidly for its concise system scheme, transient and dynamic performance. The DTC mechanism consists of voltage vector selection table, two hysteresis comparators and two estimators one for stator flux and another for electromagnetic torque. DTC is directly control torque and flux by using Voltage Source Inverter VSI, space vector and stator flux orientation and indirect speed regulated. A several control techniques can be used for improving the torque and flux performance. In this paper, the DTC with Proportional-Integral-Derivative (PID) controller used to improve the starting and dynamic performance of asynchronous motor AM, which gives good torque and flux response, best speed control and also minimize the unacceptable torque ripple. The mathematical model of DTC with PID controller of 3-phase induction motor IM are simulated under Matlab-Simulink. Therefore, the DTC based on PID controller has good performance of IM compared to classical DTC for starting, running state and also during change in load.

Abstract:
The bearingless synchronous reluctance motor (BSynRM) is a multi-variable, nonlinear and strong-coupled system. To solve the difficult problem of precise decoupling in electric torque and radial suspension force control, the theory of direct torque control of traditional synchronous reluctance motor are applied to the torque control of a BSynRM in this paper. Based on mathematical models of the BSynRM, A direct torque control algorithm based on space vector pulse width modulation (SVM-DTC) is deduced. The SVM-DTC control system is designed and simulated. The simulation results show the control algorithm of SVM-DTC realizes decoupling in electric torque and radial suspension force control. The static and dynamic performance of electric torque, speed and radial suspension force of the BSynRM is excellent.

For disadvantages of the large flux and torque ripple and current waveform distortion of Direct Torque Control (BASIC-DTC), the DTC scheme for induction motor based on torque angle closed-loop control was presented and the proposed scheme was realized with three methods of torque angle closed-loop control. The main characteristics of three methods of torque angle closed-loop control for the proposed scheme was analyzed, emphasizing their advantages and disadvantages. The performance of three methods of torque angle closed-loop control for the proposed scheme was studied in terms of flux and torque ripple, current waveform distortion and transient responses. Simulation results showed that the proposed scheme improves the performance of induction motor BASIC-DTC by combining low flux ripple, low torque ripple and low current waveform distortion’s characteristics with fast dynamics.

Abstract:
This paper presents the significant improvement of Direct Torque Control (DTC) of 3-phases induction machine using a Cascaded H-Bidge Multilevel Inverter (CHMI). The largest torque ripple and variable switching frequency are known as the major problem founded in DTC of induction motor. As a result, it can diminish the performance induction motor control. Therefore, the conventional 2-level inverter has been replaced with CHMI the in order to increase the performance of the motor either in dynamic or steady-state condition. By using the multilevel inverter, it can produce a more selection of the voltage vectors. Besides that, it can minimize the torque ripple output as well as increase the efficiency by reducing the switching frequency of the inverter. The simulation model of the proposed method has been developed and tested by using Matlab software. Its improvements were also verified via experimental results.

Abstract:
Electric drives for induction machines are of great importance because of the popularity of this machine type. To design, simulate and implement such drives, fast, reliable digital signal processors are needed. Recently Field Programmable Gate Array (FPGA) has been used in electric drive applications. This is mostly because of higher flexibility of hardware solutions compared to software solutions. In this thesis, FPGA-based simulation and implementation of direct torque control (DTC) of induction motors are studied. DTC is simulated on an FPGA as well as a personal computer. Results prove the FPGA-based simulation to be 12 times faster. Also an experimental setup of DTC is implemented using both FPGA and dSPACE. The FPGA-based design provides a potential sampling frequency of 800 kHz. This is a breakthrough knowing that a low ripple DTC is highly dependent on high sampling frequencies. Finally, a configurable torque/speed control system is designed and implemented on dSPACE.

Abstract:
This thesis is mainly devoted to the investigation of speed control methods for three phase cage induction motors with particular emphasis being given to Direct Torque Control (DTC) improved techniques.
Classical Direct Torque Control has inherent disadvantages such as: problems during starting resulting from the null states, the compulsory requirement of torque and flux estimators, and torque ripple. In the classical DTC induction motor drive a voltage vector is applied for the entire period, and this causes the stator current and electromagnetic torque exceeds its reference value early during the cycle, causing a high torque ripple. Switching cycles then follows this, in which the zero switching vectors are applied in order to reduce the electromagnetic torque to reference value. This thesis suggests a technique based on applying to the inverter the selected active states just enough time to achieve the torque and flux references values. The rest of the switching period a null state is selected which won't almost change both the torque and the flux. Therefore, a duty ratio has to be determined each switching time. By means of varying the duty ratio between its extreme values (0 up to 1) it is possible to apply any voltage to the motor. The optimum duty ratio per sampling period is a non-linear function of the electromagnetic torque error, the stator flux position and the working point, which is determined by the motor speed and the electromagnetic torque. It is obvious that it is extremely difficult to model such an expression since it is a different non-linear function per working point. Therefore, this thesis is focused on performing a fuzzy-logic-based duty-ratio controller, where the optimum duty ratio is determined every switching period. Additionally, this Fuzzy Controller is adaptive and may be applied to any induction motor.
A stator flux reference optimum controller is also designed, which not only helps to achieve a smaller torque ripple, but also reduces the reactive power consumption of the drive taken from the main supply. This is achieved by changing the stator flux reference value with reference being made to the correspondent torque reference value. Therefore, the stator flux reference value chosen is to be just of sufficient value to produce the desired torque
Simulated results are shown in order to compare the classical DTC and the Fuzzy Logic based DTC.
The control algorithms have been implemented on a PC/DSP based board that facilitates the use of parallelism in software design. A 1.5kW, three-phase induction motor drive has been designed and experimental data obtained from it in order to verify the results achieved by simulation.

Thesis (MScEng)--Stellenbosch University, 2013.
Wind energy has proven to be a viable source of clean energy, and the worldwide demand is growing rapidly. Variable speed topologies, with synchronous generators and full-scale converters, are becoming more popular, and the e ective control of these systems is a current trend in wind energy research. The purpose of this study is the modelling, design, simulation and implementation of a small-scale, variable speed wind energy conversion system, incorporating the position sensorless direct torque control with space vector modulation, of a permanent magnet synchronous generator, including an RLC converter lter. Another aim is the development of a gain scheduling algorithm that facilitates the high level control of the system. Mathematical models of the combined lter-generator model, in the stationary and rotating reference frames, are presented and discussed, from which equivalent approximate transfer functions are derived for the design of the controller gains. The design of the controller gains, RLC lter components, gain scheduling concept and maximum power point tracking controller are presented. It is discovered that the RLC lter damping resistance has a signi cant e ect on the resonance frequency of the system. The system is simulated dynamically in both Simulink and the VHDL-AMS programming language. Additionally, the maximum power point tracking controller is simulated in the VHDL-AMS simulation, including a wind turbine simulator. The simulation results demonstrate good dynamic performance, as well as the variable speed operation of the system. The practical results of torque and speed controllers show satisfactory performance, and correlate well with simulated results. The detailed gain scheduling algorithm is presented and discussed. A nal test of the complete system yields satisfactory practical results, and con rms that the objectives of this thesis have been reached.

Abstract:
1.1 Objectius de la tesi.
En els últims anys el control del parell i de la velocitat del motor d'inducció ha estat llargament estudiat. Un cop s'ha considerat que les prestacions dinàmiques assolibles eren ja suficientment satisfactòries, els diferents investigadors han reorientat els seus esforços cap a altres enfocs relacionats, ja no únicament amb el MI estrictament parlant, sinó amb tot el sistema que constitueix l'accionament amb si mateix.

L'objectiu principal d'aquesta tesi és posar en evidència, l'existència d'unes idealitzacions i limitacions dels controls tradicionals de parell i velocitat del motor d'inducció (bàsicament del Control Vectorial i del DTC), així com a proposar mètodes i algorismes alternatius que superin a les mateixes.

1.2 Estructura i contingut

El Capítol 1 conté una introducció al treball.

El segon capítol Modelització del motor d'inducció, presenta les principals tècniques i equacions, que porten a descriure d'una forma dinàmica al MI.

El tercer capítol, Control de parell i velocitat del MI, es descriuen els Control Vectorial i el Control Directe de Parell (DTC), ja que són els més estudiats en la literatura.

El quart capítol, Estudi dels bucles de corrent, tracta més en profunditat una de les limitacions que presenta el Control Vectorial, l'estudi de les interaccions que hi ha entre els dos llaços de regulació de les intensitats de l'estator (la seva component directa i en quadratura).

En el cinquè capítol, OSVPWM (Optimized Space Vector PWM), es presenta un estudi detallat dels diferents mètodes d'ondulació (DC/AC) que existeixen. D'entre tots aquests, s'estudia amb molt més deteniment el Space Vector PWM (SVPWM), aportant un nou algorisme d'implementació del mateix (optimitzat per DSP's), així com posant en evidència la negativa influència dels temps morts sobre el mateix.

El sisè capítol presenta l'ODTC (Optimized Direct Torque Control), com a resum de tots els capítols anteriors.
1.3 Aportacions d'aquesta tesi.

En la modelització matemàtica del Motor d'Inducció, s'ha arribat a la formulació d'una equació genèrica, que engloba totes les possibles referències, i totes les definicions d'intensitats magnetitzants.

En l'estudi del DTC s'ha presentat una nova taula de commutació, que permet disminuir l'excessiu arrissat de parell que presenta la taula de commutació tradicional.

En l'estudi del SVPWM s'ha presentat una nova formulació molt més apta per a la seva implementació en DSP (Digital Signal Processor). Igualment, s'ha posat en evidència la important influència dels temps morts dels interruptors, en la THD (Tasa de Distorsió Harmònica) de l'ona de tensió de sortida de l'ondulador proposant un algorisme de compensació (OSVPWM).

S'ha proposat un nou algorisme de control del parell del MI, incorporant les prestacions del DTC en règim transitori (ràpida resposta del parell), i les prestacions del Control Vectorial en règim permanent (petit arrissat de parell), amb la incorporació de l'OSVPWM com a estratègia de modulació.

Finalment destacar, l'aportació d'un equip experimental basat en DSP, de disseny molt versàtil i robust, i que incorpora tota una sèrie d'eines de desenvolupament que el fan molt útil per a l'experimentació de noves lleis de control, referides principalment al motor d'inducció, però que també s'ha demostrat eficient alhora de treballar amb altres plantes com és el cas dels SAI's (Sistemes d'Alimentació Ininterrompuda).

1.4 Futures línies de recerca.

Seguir treballant en l'estudi del OSVPM, però en el cas de la sobremodulació, és a dir, quan la tensió de consigna superi o surti fora dels rangs d'aplicabilitat del mateix.

Amb l'obtenció de l'equació que ens permet estimar l'arrissat màxim de parell, associat al conjunt motor-ondulador, estudiar el disseny de controladors per histèresi de banda d'histèresi variable (funció de l'estat de l'accionament).

Finalment destacar, que amb el constant augment de la potència de càlcul dels DSP, les possibilitats de noves lleis de control del MI ("fuzzy logic" i "passivity control") són cada dia més possibles, i per tant s'han convertit en una línia de treball molt interessant.

Abstract:
The objective of the dissertation is to develop simplified analytical models for typical linear-motion and rotary-motion energy-conversion systems under active DC excitation without tedious numerical-simulation effort, and provide practical implementation of the models in optimal-design and thermal-protection aspects. The model of a vacuum automatic circuit recloser (a typical linear-motion system under DC excitation) is first developed in the form of a non-linear discontinuous eighth-order dynamic system. The model is then used to simulate the transient mechanical and electromagnetic performance during the opening and closing movements of the recloser. Such a model is not found in the literature. Although the model is based on certain simplifying assumptions, the result is validated by high-speed-camera measurements. In addition, the impact of key design variables is explored, based on which an improved recloser design is proposed, and helps to optimize capital and production costs without degrading performance. Further analytical investigation is carried out in modeling an inverter-fed induction motor (IM) (a typical rotary-motion system) with active DC injection. The IM is closed-loop controlled via two popular motor-control algorithms, namely, the direct-torque-control (DTC) algorithm and field-oriented-control (FOC) algorithm. Quantitative relationships between the changes of various machine variables during the active DC excitation are provided in the theoretical analysis. The developed DC-injection model is further simplified for practical implementation. The developed IM model under DC injection results in practical ways to excite a proper amount of DC current directly or indirectly into IM stator windings via different closed-loop motor-control algorithms. In a DTC motor-drive system, the modeling work makes it possible to excite the DC current indirectly inside the motor by superimposing a stator-flux-linkage-bias command in the flux-control loop or a torque-ripple command in the torque-control loop. The proposed flux-linkage-injection and torque-injection methods are the first novel efforts to implement the DC-signal-injection method in a DTC motor-drive system. In addition, the analysis carried out in a standard FOC drive system brings about an improved DC-current-injection approach: the torque ripple in this method is significantly mitigated compared to all existing DC-injection methods in FOC systems. The proposed DC-injection methods, either in a DTC or an FOC system, lead to a simple, low-cost, accurate, and non-invasive thermal-monitoring scheme for closed-loop-controlled IMs, where the stator temperature is indirectly estimated from stator resistance. Furthermore, considering inverter non-idealities, there is a challenge for a typical inverter drive to accurately estimate the DC component of motor terminal voltages. The existing methods are extended to provide a complete study of the real-time signal-processing technique for both DTC and FOC algorithms, and are finally implemented in a custom-built programmable motor-drive system. The experimental results demonstrate that the proposed technique gives accurate and robust stator-temperature estimation, regardless of the operating conditions and cooling modes. The analytical modeling method for the linear-motion and rotary-motion energy-conversion systems can be further extended to other power devices with similar mechanisms, and implemented in optimal design, control, and thermal-protection areas.

The operating limits of PMS machines under DTC are presented in terms of current limit, voltage limit, and flux linkage limit. Also, flux linkage control, including maximum torque per ampere (MTPA), unity power factor, and flux weakening at high speed, is derived. Then, alternative DTC schemes, including different SVM-DTC schemes, are presented. In line with the increasing energy-saving tendency in industrial applications, major emphasis is placed on the loss minimization of DTC. Finally, a comprehensive comparison was made between the basic DTC and vector control, emphasizing the pros and cons of DTC with respect to vector control.

The fundamental principles of the methods are explained, the machine models appropriate to the methods are derived, and the control systems are explained. The PMS motor performances under the control systems are also investigated. It is elaborated that MPC is capable of controlling the motor under an optimal performance according to a defined objective function. DBC, on the other hand, provides a very fast response in a single operating cycle. Finally, combined control produces motor dynamics faster than one under VC, with a smoother performance than the one under DTC.
