ABSTRACT:
A circuit generates phase pole command signals for controlling operation of an induction motor. To minimize instabilities occurring within the motor, a stability control circuit generates a phase shift signal, which is input to reference signal generators to adjust phase reference signals. When in a motoring mode, the phases of the reference signals are advanced monotonically with respect to the electro-motive force of the induction motor. When in a regeneration mode, the phases of the reference signals are decreased monotonically with respect to the electro-motive force. The resulting adjustment to the phases of the reference signals minimizes instabilities within the feedback control of the induction motor.
