Genetic Algorithm Tuned PI Controller on PMSM Direct Torque Control

Abstract

This paper presents the Direct Torque Control (DTC) strategy for the Permanent Magnets Synchronous Machine (PMSM) with tuning the PI controller by using genetic algorithms to ensure optimal performance it allows reducing the ripples of the torque and flux. A genetic algorithm is used to optimize the gains of the PI controller forgiven the reference of the torque. Simulation results verified the performance of the proposed approach. The simulations result of this technique is justified the minimization the ripples of switching in the inverter and reduces the harmonious of the torque and the stator current.
