Abstract: Technical solutions are described for a motor control system that includes a feedforward control module to control an output torque generated by the motor. The feedforward controlling includes computing a first voltage command for the motor based on an input torque signal. Further, the feedforward controlling includes computing a second voltage command for the motor based on a brush drop voltage of the motor and a back-EMF drop voltage of the motor. Further, feedforward controlling includes computing a voltage command for the motor by summing the first voltage command and the second voltage command. Further yet, the feedforward controlling includes sending the voltage command to the motor for generating the output torque.

Abstract: Technical solutions are described for a control system that includes a current command module configured to receive a torque command and output a current command for controlling a direct current (DC) motor, and a regenerative current limiting module configured to receive a regenerative current limit as an input and actively compute a motor current limit based on the regenerative current limit, the regenerative current limiting module configured to limit the current command based on the motor current limit.
