Abstract :
The problem of controlling the π-model induction motor with magnetic saturation is considered in this proposed research. Direct Torque Control (DTC) of induction motor has been developed since three decades. Furthermore many techniques have been proposed to improve the performance of the induction machines that using the DTC drives in industry. However, all the previous models are based on the linear model of the machine for approximation. This is not the exact model and there is no guarantee that the process will work outside the saturation region of the flux, especially in large rating of induction machines. In this paper, two types of voltage source inverters are applied on the saturated model of induction motor. We study the performance of the induction machine response in the two cases using MATLAB SIMULINK one is by using torque control and the other is by using speed control. GA and PSO are used for improvement of the speed control for the two and three level inverters.
