This paper presents theoretical analysis and experimental verification of the direct torque control (DTC) for permanent magnet synchronous motor (PMSM) drive. PMSM drive is characterized by the direct torque control based on space vector pulse-width modulation (SVPWM) method which is controlled by digital signal processor (DSP). Since the constant switching frequency is produced by SVM technique,...
This work focuses on providing sensorless DTC for IPMSM with minimum torque ripple and at the same time with a simple algorithm to be implemented with hardware. The developed algorithm method follows the principle of steering that corrects the direction of vehicle from deviation. The algorithm uses the output of two hysteresis controllers used in the traditional HDTC to determine two adjacent active...
The paper presents a fuzzy logic controller (FLC) for permanent magnet synchronous motor (PMSM). The fuzzy logic controller is used for speed control of this type of motors. The dynamic response of (PMSM) with the proposed controller is studied during the starting process and under different load disturbances. The effectiveness of the proposed fuzzy logic controller is compared with that of the conventional...
