A Comparative Study of PI and IP Controllers For Field Oriented Control of Three Phase Induction Motor


In this paper, Field Oriented Control (FOC) of 3-phase induction motor iscontrolled by using (PI) and (I-P). These controllers are established with the help ofMATLAB/SIMULINK. The gains value obtained by the trial and error method of PIcontrollerand Particle Swarm Optimization (PSO) technique is used in this paper fordesigning I-P controllers that give better performance. PSO technique was proposed totune the optimal gains of I-P controller and state feedback gains. A comparison betweentwo controllers is presented. From simulation results, the advantages and disadvantagesof both controllers are investigated to explain the characteristic of the two methods. Theoperation perforamcnes of the two proposed controller systems have been examined interms of the motor torque, current ripples and momentary responses to load toquevariants.
