Particle Swarm Optimization (PSO) is an excellent stochastic approach based on swarm intelligence which is used for solving continuous and discrete optimization problems. This simple and effective technique can be applied to induction motor drives to get ideal performance. Hence, this paper presents a Direct Torque Controller (DTC) based on PSO. The main objective of this work is to have an improved stator flux response by optimizing the parameters (Kp, Ki) of the Proportional- Integral (PI) controller using PSO technique. A DTC model is constructed with a PSO PI controller and simulated in MATLAB/SIMULINKR. The results of simulation show nearly good performance of the PSO tuned PI controller.

Keywords: Particle swarm optimization technique, Direct torque controller, PI controller.
