A fuzzy pre-compensated-PI controller for indirect field oriented controlled induction motor drive

This paper presents design, analysis and simulation of fuzzy logic controller for indirect field oriented control (FOC) of induction motor drives. The induction motor drive is controlled using a FOC, which allows a fast transient response of the system by controlling a decoupled flux and torque components. Moreover, a fuzzy pre-compensated proportionalintegral (PI) controller is used for attaining a better dynamic performance of the proposed drive system. The performance of the proposed fuzzy controller is compared with the conventional-PI controller for the operation of the induction motor drive at rated load and light loading conditions. The obtained results demonstrate effectiveness and robustness of the proposed fuzzy logic controller.
