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.

In this paper vector control with variable frequency drive used toapply speed control of a three-phase AC Asynchronous and induction machines.The flux and torque references used to obtain the current components.Proportional-Integral controllers are used to keeping the measured currentcomponents at their reference values. The stator voltage references are theoutput of the PI current controllers. High-performance with the smoothoperation is obtained using the proposed method. The differences can be seen inbehavior dynamic state. When the motor is rotating at full speed with a fullload,it reaches good current waveforms very easily due to the independent PIcontrol of torque and magnitude of flux. In high and sudden variations of thereference input, the direct command is more efficient and less demanding forthe equipment. The expressions of the fundamental variables (speed, torque,flux) and equivalent phase circuit of the machine will be reviewed.
