Abstract:

There is increasing demand for simple motor drives offering high reliability and fault tolerance in applications such as the aerospace actuator industry, with the development of `more electric aircraft'. This thesis presents a motor drive employing a switched reluctance motor, the novel single sided matrix converter, and a novel double band hysteresis based control scheme for control of the converter, implemented using a field programmable gate array (FPGA). The single sided matrix converter is a direct energy converter, capable of supplying unidirectional currents from a multiphase AC voltage

Abstract:

AC induction motor speed control has traditionally involved controlling the motor's input voltage and frequency through use of a three phase pulse-width-modulating (PWM) controlled-voltage inverter, where the inductive motor load acts as an integrating filter to smooth out the motor input currents. This report describes the development of a novel controlled-current inverter system in which the three phase motor input currents are independently monitored the inverter phases are independently switched to ensure that the three phase motor currents are balanced three phase sinusoids at all times.

Abstract:

Control and balancing of an inverted pendulum has gained a lot of attention over the past few decades due to its unstable properties. This has become a great challenge for control engineers to verify and test the control theory. To control and balance an inverted pendulum, proportional integrated derivative (PID) method or linear quadratic regulator (LQR) method can be used through which a lot of simulations can be done using the represented theories.Since urban population is increasing at a very alarming rate, there is a need to discover new ways of transportation to meet the future challenge

Abstract:

Electrical power demand in aircraft has grown significantly over the last century, and this trend continues with the More Electric Aircraft (MEA) and All Electric Aircraft (AEA) concepts. Higher voltages such as 270VDC are required to deliver additional power to loads and to optimise aircraft mass. Increased voltages inflict more stress on the Electrical Wiring Interconnect System (EWIS) and increase the impact of series arc faults caused by wiring defects. Solid State Power Controllers (SSPCs) are used to provide fast protection in high voltage distribution systems. The aim of this work is th

Abstract:

This dissertation focus on a Maximum Torque per Ampere (MTPA) control scheme for a non-linear synchronous reluctance motor (Sync-Rel). Due to the absence of permanent magnets, Sync-Rel motors have poor torque production capability and relatively low power factor. Therefore, it is important to maximize the torque given the maximum current of the power inverter. In the classical solution to the MTPA control problem, the d-q current components are considered equal. This solution assumes a linear magnetic circuit for the Sync-Rel motor. In practical applications, the Sync-Rel motor has a non-line

In the nearest future, the human driver is viewed as a reliable backup even for the fully automated road motor vehicles (cars). Indeed, the driver is assumed to swiftly take the control of the car in cases of suddenly occurring (i) challenging environmental conditions, (ii) complex unforeseen driving situations, or (iii) degradation of performance of the car. However, due to the cognitive overload in such a sudden, stressful takeover of the control, the driver would often experience the startle effect, which usually results in an unconscious, instinctive, yet incorrect response.

碩士<br>國立臺灣科技大學<br>電機工程系<br>100<br>This thesis aims to implementation a speed sensorless speed and current controller for permanent magnet brushless DC motors (PMBLDC Motor) with an FPGA (Field Programmable Gate Array) chip.In order to replace position or speed sensors, this study proposes an indirect way to extract the motor’s communication signal from motor’s terminal voltages with simple RC lowpass filters and one-stage comparators. The speed and current PI digital controllers are designed using Verilog hardware design language to realize motor speed and average communication current control

碩士<br>國立臺北科技大學<br>電機工程系所<br>93<br>In general, applying traditional artificial neural network structure to control systems requires off-line learning and training to obtain the optimal parameters. However, it is not easy to get suitable training data and as a result the performance of response of designed control system is not as expected in such circumstances. Therefore,to improve the drawbacks of on-line learning and adaptation properties under the traditional Artificial Neural Network architecture, this paper adopts the projection algorithm in adaptive theory to the Neural Network and a so-c

An incremental algorithm is used to estimate the flux linkage increments, which eliminates the integration involved in the flux linkage estimation. This fea

Abstract:

碩士<br>國立臺灣海洋大學<br>電機工程學系<br>103<br>This thesis presents two predictive current controllers, namely the model-based predictive current controller, the model-free predictive current controller, and the simplified predictive current controller, applying to a synchronous reluctance motor. The later two predictive current controllers are based on the current variation detection technique; therefore,it is not necessary to use parameters of motor and back-EMF in current prediction algorithms. Compared to the model-free predictive current controller, the simplified model-free predictive current contro

碩士<br>國立臺灣科技大學<br>電機工程系<br>106<br>Synchronous Reluctance Motor (SynRM) has drawn great attention due to its simple structure, good robustness, and no permanent magnet material. This thesis proposes a systematic design and implementation of a model-based predictive speed controller and current controller for SynRM drive systems. The model-based predictive controllers require motor parameters such as resistance, inductance, and back EMF. Although the parameters are varying every sampling interval, the proposed controllers can adapt well due to the augmented state variables and constraints. As a

Abstract:

This paper presents a comparative study of speed control of a separately excited DC motor by using different type of controllers. Speed of separately excited DC motor can be varied below and above the rated speed by various techniques. It can be varied above rated speed by field flux control and below rated speed by terminal voltage control .Conventional controllers are commonly being used to control the speed of the DC motors in various industrial applications. It’s found to be simple, robust and highly effective when the load disturbance is small. But during high load or rapid variation of l

Abstract:

In DC to AC power conversion, voltage source inverters (VSI) based current controllers are usually preferred for today’s high performance AC drive which requires excellent dynamic and steady state performances at different transient and load conditions, with the additional advantages like inherent short circuit and over current protection. Out of different types of current controllers, hysteresis controllers are widely used due to their simplicity and ability to meet the requirements for a high performance AC drives. But the conventional hysteresis controllers suffers from wide variation of PW
