Vector Control of Induction Motor Using ANN and Particle Swarm Optimization

-This paper presents the scheme of vector control of Induction Motor using three different types of speed controllers, conventional PI controller, ANN speed controller and PI controller, for which parameters are optimized using Particle Swarm Optimization technique. The disadvantage of the PI controller like slow response and large settling time are avoided using the ANN speed controller. The data used to train the ANN controller is taken from the simulation of conventional controller. As the third method particle swarm optimization technique was used to optimize the parameters of PI controller by considering the maximum peak overshoot as the error function. The advantage of the optimized controller is there is no need to change in the design part of the vector control scheme. The simulation results indicate the optimized controller possesses excellent dynamic response at all reference speeds. The results for conventional controller, ANN controller and optimized controller are shown at the end. Key words--Vector Control, PI controller, Particle Swarm Optimization (PSO)
