A new and simple structure of fuzzy logic based indirect field oriented control of induction motor drives

This paper presents a novel speed control scheme using a new and simple structure of fuzzy logic controller (FLC) for an induction motor (IM) drive. The proposed FLC is developed to have less computational burden, which makes it suitable for real-time implementation. The parameters of the FLC are tuned by genetic algorithm (GA). The complete drive incorporating the FLC is successfully implemented in real-time using a digital signal processor board DS 1102 for a laboratory 1 hp induction motor. The efficacy of the proposed FLC based IM drive is verified by simulation as well as experimental results at various dynamic operating conditions. The proposed FLC is found to be a robust for high performance industrial drive applications.
