The paper deals with the fuzzy logic control(ler) (FLC) application to the field-oriented AC motor drive. Some fundamentals of the FLC are illustrated. The aspects of major importance in the application to field-oriented AC motor drives are pointed out and discussed. A FLC field-oriented drive is designed, simulated and experimented in a speed control loop. The results are compared with those obtained on the same drive with conventional digital PI type speed controller.
