Fuzzy rule-based model reference adaptive control of permanent magnet synchronous motor drive

The paper presents a model reference adaptive control scheme using fuzzy logic adaptation mechanism to generate additional signal to the system input. The proposed method has been applied to the linearized model of the angular speed control system of a vector controlled chopper-fed permanent magnet synchronous motor (PMSM) drive. Simulation results indicate that a good adaptation is achieved even for large parameter variations. Marked simplicity and digital character of the method make it very suitable for microcomputer implementation.
