Abstract: A polyphase bidirectional control system suitable for use with AC motors of the squirrel cage type. In response to applied actual and desired position signals, the present invention generates a position error signal and a motor speed control signal; the speed control signal having a variable pulse width and pulse repetition rate. The control signal is employed to supervise the application of power to the motor to be controlled while the position error signal is employed to control the direction of operation of the motor.
