Abstract:
Technical solutions are described for disturbance feedforward compensation technique for improving the disturbance rejection properties of a closed loop position control system. According to one or more embodiments, a steering system includes a position controller that generates a torque command based on an input rack-position command and a measured position command. Further, a disturbance estimator that estimates a rack force acting on a rack, and an adder generates an adjusted torque command by adding the rack force that is estimated into the torque command. The steering system further includes an actuator that positions the rack according to the adjusted torque command.
