Based on the two-stage strategy and the heuristics deduced from the field-oriented principle, a hybrid fuzzy/PI controller is proposed in this chapter. A fuzzy logic controller provides frequency control during the acceleration/deceleration stage, giving a large torque. A PI controller provides speed control by regulating the current magnitude during the steady-state stage. The performance of the two-stage controller approximates that of a field-oriented controller. Besides, the new controller has the advantages of simplicity and insensitivity to motor parameter changes.
