The paper presents a fuzzy logic controller (FLC) for permanent magnet synchronous motor (PMSM). The fuzzy logic controller is used for speed control of this type of motor. The dynamic response of (PMSM) with the proposed controller is studied under different load disturbances. The effectiveness of the proposed fuzzy logic controller is compared with that of the conventional PI and PID controllers. The proposed controller is used in order to overcome the nonlinearity problem of PMSM and also to achieve faster settling response.
Key words: Speed control, plus integral controller, fuzzy logic controller, permanent magnet synchronous motor
