Comparative study between several strategies speed controllers in an indirect field-oriented control of an induction machine

In this paper, a comparative study between different controllers is made. The sliding mode controller, the self tuning fuzzy logic controller, the fuzzy logic controller and the classical PI controller are applied to control an induction machine. The simulations results showed that the sliding mode controller and the self tuning fuzzy logic controller provide very good performance. In fact, the sliding mode controller is characterized by a high resistance to the perturbations of the machine parameters and the self tuning fuzzy logic controller is advantageous in terms of response time. Whiles fuzzy logic controller presents the better performances compared to the classical PI controller.
