Abstract: The paper describes an application of the fuzzy algorithm on proportional-integral (PI) speed controller, then the coefficients of the controlled system are optimized by genetic algorithm (GA) to find optimal parameters for the PI speed controller in the controlled structure of the A.C. drive with the vector controlled. An induction motor model with the PI speed controller is presented in the first section. The second part describes the design of the online PI-fuzzy speed controller and GA tuned for coefficients of system. Finally the important simulations with the traditional PI speed controller and the online PI-fuzzy speed controller using the tuned genetic algorithm together with change of parameters were performed in the Matlab-Simulink environment. The simulation results show that the online PI-fuzzy speed controller with the tuned GA produces a much better response of the induction motor speed. |
