An Improve Fuzzy Proportional Integral and Derivative Controller for Torque Ripple Reduction in Six-Phase Induction Motor in HEV

Abstract

In this paper, for the reduction of torque ripples in six-phase induction motors, a hybrid controller is proposed that combines a well-defined control strategy for the motor operation. The direct and field-oriented control are hybrids that use a stationary and synchronous reference frame with the stator and rotor as control variables. The control variables concerning both the stator and the rotor are controlled using a novel controller named fractional order fuzzy proportional integral and derivative controller. Due to the high-level inverter, more complex voltage vectors are generated for the control along with the optimized selection of the switching sequence for the inverter an artificial neural network is utilized. From the analysis, only 0.8% of torque ripple and harmonics of 2.45% is seen.
