Abstract:

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 vectors. It also uses the magnitude of the torque error and stator flux linkage position to select the switching time required for the two selected vectors. The selection of the switching time for the selected vector consider the system inertia and control time delay utilizes a new suggested table structure, which reduces the complexity of calculation. The simulation and experimental results of this proposed algorithm show adequate dynamic torque performance and considerable torque ripples reduction as well as lower harmonic current as compared to traditional HDTC.
