摘要: A direct current motor control system for generating current command signals to a unidirectional armature controller and a bidirectional field controller. A motor speed command is compared with the actual motor speed to generate a speed error signal. The system generates a current command signal from the average of the speed error signal wherein the current command signal is proportional to the square root of the desired motor torque. The absolute value of the current command signal is the input to the armature controller and the field controller receives the current command signal wherein the polarity of the signal determines the direction of current flow in the field winding for controlling the direction of rotation of the motor.
