Abstract
A control for energizing a DC motor to provide improved speed regulation to the motor under transient conditions. The control includes a regulating circuit having an output signal controlling the armature voltage applied to the motor. An input speed reference signal corresponding to the desired speed of said motor is provided to the regulating circuit. An input armature voltage feedback signal is also provided to the regulating circuit to produce an error signal for operating said regulating circuit to establish the armature voltage, and hence the speed of said motor. The armature current of the motor is sensed and a signal corresponding to the voltage drop resulting from the inductance of the armature circuit provided to the regulating circuit for altering the output of the regulating circuit in a manner tending to establish the speed of said motor at that established by said speed reference signal. An IR compensating circuit provides an IR compensating signal to the regulating circuit.
