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.
