An optimized FOC method for three-phase induction motor drives using PSO algorithm

This paper proposes a modified Field-Oriented Control (FOC) method for three-phase induction motor drives. In this method, double Proportional-Integral (PI) regulators instead of the conventional PI regulators are used. In addition, a simple algorithm based on the Particle Swarm Optimization (PSO) approach is presented to tune the parameters of double PI regulators. In other words, the proposed FOC approach is a modification of the conventional FOC technique where optimized double PI regulators are utilized to improve the performance of the three-phase induction motor drive system. The proposed FOC method improves the quality of the system during dynamic and steady-state conditions. The simulation results of the proposed FOC process are compared with the results of different FOC methods for a three-phase induction motor drive system using the Matlab/Simulink software. The results in this paper show the strength and effectiveness of the suggested FOC technique.
