Abstract :
This paper presents a new method to control a synchronous reluctance motor. A study of the sliding mode with fuzzy controller design for a synchronous reluctance motor without using any position or speed sensor is presented. The system has a fast response and a good disturbance rejection capability. First, the position, speed, and acceleration signals are obtained by detecting the voltages and currents of the motor. Then, a sliding mode with a fuzzy controller is designed to achieve a high performance drive system. The chattering of the speed response is reduced by using the fuzzy control to adjust the sliding Line. Next, the system is enhanced by using a high performance 32 bit DSP and simple hardware circuits. Finally, some experimental and computer simulation results are shown to verify the theoretical analysis. This paper proposes a new control method for a synchronous-reluctance-motor-drive system
