Abstract:

Recently, permanent magnet assisted (PMa)-synchronous reluctance motors (SynRM) have been considered as a possible alternative motor drive for high performance applications. In order to have an efficient motor drive, performing of three steps in design of the overall drive is not avoidable. These steps are design optimization of the motor, identification of the motor parameter and implementation of an advanced control system to ensure optimum operation. Therefore, this dissertation first deals with the design optimization of the Permanent Magnet Assisted Synchronous Reluctance Motor (PMa-SynRM

A microprocessor control scheme for variable speed switched reluctance motor(SRM) drives is discussed. A particular implementation derived from first principles of the SRM is presented. The Intel 8088 microprocessor is used for the design implementation. It is shown that given the control requirements of the SRM like firing different phases according to rotor position and phase currents, a microprocessor controller is a good choice. The controller is economical since it uses standard TTL chips. The slow response at low speeds is also discussed. Experimental results performed on a static induct

In this thesis different methods of optimizing line start permanent magnet motor (LSPM) for magnet cost reduction is studied. Influence of different parameters has been studied by simulating magneto-static and transient FEM models of the machine. Finally a motor design of a LSPM with high rotor saliency has been proposed. The first method investigated is the use of flux barriers in LSPM and its effect on the magnetic flux leakage. The flux barriers reduce the flux leakage and hence help in reducing magnet volume.

This aspect has become even more critical due to the price instability of the rare-earth elements.

Abstract:

Nowadays, the interest in the synchronous reluctance machines is growing up due to their several merits in comparison to other machine types. These machines offer high torque density with respect to the induction machines. Their torque density is slightly lower than permanent magnet synchronous machines even though the lower performance is compensated by a much cheaper rotor. Since synchronous reluctance machines do not induce voltage when the stator is not supplied, there are not short circuit currents and braking torques due to the electrical faults, e.g. they have high fault tolerant capab

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

碩士<br>國立雲林科技大學<br>電機工程系碩士班<br>97<br>This thesis presents the research of chaotic phenomenon for the synchronous reluctance motor. Chaotic phenomenon looks like confused but it is regular. Chaotic phenomenon happens due to nonlinear characteristic of the systems. System parameters and initial value variations cause the output dramatically. Dissimilar system need not cause chaotic phenomenon in the same method because every motor’s parameters are different.. We establish the synchronous reluctance motor chaos model, the equilibrium points and characteristic equation by motor model. We utilize th

The wearable device consists wireless Bluetooth and optics Oximeter spec which monitors user heart rate and oxygen data to any Bluetooth receiver. We used health care wearable device with SynRM to design the breathing assistance system. Firstly, we used the mathematical model equation of SynRM and maximum torque control algorithm to control motor command current. Secondly, we proposed robust compensation with adapti

碩士<br>國立雲林科技大學<br>電機工程系<br>104<br>In this thesis, we propose wearable device to apply in health care system. Synchronous reluctance motor(SynRM) uses speed predictive algorithm to drive oxygen supply system which provides user proper oxygen. Wearable device uses MSP430 low power consumption chip to achieve long time use. Oxygen rate is an important index of health. Long-term oxygen rate surveillance makes medical staff to know the user’s health conditions. Medical staffs know the user healthy or not by user’s physiological parameters of wearable device. This wearable system provides user a bet

碩士<br>國立雲林科技大學<br>電機工程系碩士班<br>101<br>This thesis develops a digital signal processor (dSPACE inc. DS1104) based synchronous reluctance motor (SynRM) drive system. Elman neural network and modified Elman neural network controller are proposed in the SynRM when the SynRM has parameters variations and external disturbances. Recurrent Neural Network (RNN) and Elman neural network (ENN) are compared which ENN has faster convergence for special recurrent structure. The on-line parameters learning of the neural network used the back-propagation (BP) algorithm. We use the discrete-type Lyapunov functi

The activation function of the back-propagation network (BPN) is replaced by wavelet function in WNN. Wavelet transform of WNN controller has time domain and scale analytical capabilities. Neural network of WNN controller has high fault tolerance for inexact information and strong learning ability. The recursive structure of wavelet neural network controller is also presented in this thesis. The recursive wavelet neural network (RWNN) controller has better co

碩士<br>國立成功大學<br>電機工程學系<br>105<br>In this paper, the direct torque control on synchronous reluctance motor and the flux Luenberger observer scheme are proposed to avoid the error accumulation and the stator voltage-drop caused by the back electromotive force integral in the traditional flux estimation. Three simulation software, i.e., Maxwell, Simplorer and MATLAB were used to implement the multi-physics coupled-simulation for designing the model of the synchronous reluctance motor direct torque control. MATLAB simulation was used to build the direct torque control model for determining the swi
