Abstract:
-Torque ripple minimization using simple reference controlled Hysteresis current controller is proposed in this paper. An ideal BLDC motor has trapezoidal back EMF waveform. Non-uniformity of magnetic material and design parameters are some of the practical reasons which disturb the production of exact trapezoidal wave shape. This paper introduces reference controlled Hysteresis current controller to minimize torque ripple. Performance analysis of the proposed system is analyzed using Matlab and compared with an un-ideal back EMF method. Validation of simulation analysis is proposed using the embedded system based hardware with FHP BLDC motor.
