Fuzzy logic based speed control of an IPM synchronous motor drive

This paper presents the fuzzy logic-based speed control of an interior permanent magnet synchronous motor (IPMSM) drive. The fundamentals of fuzzy logic algorithms related to motor control applications are illustrated. A new fuzzy speed controller for the IPMSM drive is designed. The efficacy of the proposed fuzzy logic controller (FLC) based IPMSM drive is verified by simulation as well as experimental results at different dynamic operating conditions. The fuzzy logic controller is found to be robust for application in the IPMSM drive. The complete vector control scheme incorporating the FLC is implemented in real-time using a digital signal processor (DSP) controller board DS 1102 in a laboratory 1 hp interior permanent magnet synchronous motor.
