Approach to fuzzy control of an indirect field-oriented induction motor drives

The field orientation control of an induction motor has been permitted fast transient response by decoupled torque and flux. The conventional PI controller has been widely used in industrial applications due to the simple control algorithm and easy implementation. With help of the Matlab/Simulink, a block model of an induction motor drives can be constructed. This paper presents a novel fuzzy controller of an indirect field oriented induction motor drive for high performance applications. The superiority of the proposed fuzzy controller over a conventional PI controller in handling nonlinear systems such as induction motors has been effectively demonstrated by comparing this speed controller with a conventional PI controller under varying operating conditions like step change in speed reference and torque reference. The results validate the robustness and effectiveness of the proposed fuzzy logic controller for high performance induction motor drive systems
