ABSTRACT:
In a vehicle with an electric power steering system, an electric power steering control apparatus comprising a torque sensor outputting a torque signal indicative of steering column torque, a controller receiving the torque signal and, responsive thereto, providing a motor current command, an electric motor providing power assist to the electric power steering system responsive to the motor current command, and a compensating filter, within the controller, receiving the torque signal and providing a transfer function operation thereon, wherein the motor current command is responsive to the output of the compensating filter and wherein stability margins of the system are enhanced.
