This paper presents a novel fuzzy position controller (FPC) for an interior type permanent magnet synchronous motor (PMSM). The FPC is employed as an outermost control-loop in a closed-loop vector control scheme of PMSM drive. A synchronous frame proportional–integral (PI) controller is employed as an inner speed control loop. The controllers are designed based on the indirect field oriented control. The control scheme can be used for both position and speed control applications by enabling and disabling the position controller, respectively. The control scheme is implemented using Digital Signal Processor TMS320C31. The performance of the proposed control scheme for a PMSM servo-motor drive is investigated both theoretically and experimentally at different operating conditions. The performance of the proposed FPC is found robust for industrial applications.
