Abstract

 In this paper, DIRECT TORQUE CONTROL of INDUCTION MOTOR with SPACE VECTOR MODULATION (DTC-SVM) is presented, which is comprised of two PI controllers, the first one is for torque controlling and another one is for flux controlling. Due to the characteristics of nonlinear control systems, classic controllers do not work well in different conditions. In this paper the flux controller is classic PI controller (CPI). A fuzzy controller is used for regulation of PI coefficients. It is used of a PARTICLE SWARM OPTIMIZATION (PSO) algorithm to get optimized parameters for classic controllers of torque and flux. In this paper, the performance of the proposed drive is tested in various operating conditions And has been shown that the use of fuzzy self-tuning PI controller (STFPI) provide better condition than the classic form and Improves the dynamic response of drive. Obtained Simulation results in Matlab/Simulink confirms the correction of proposed algorithm.
