Abstract
An electric motor of an electric power steering assembly is activated in response to a response signal. The response signal includes a baseline control torque signal generated by a baseline controller and an auxiliary control torque signal generated by a disturbance rejection controller. At least one operating parameter of the electric power steering assembly is estimated as a function of the baseline control torque signal. The at least one operating parameter is also measured. An error amount is determined as a function of the at least one measured operating parameter and the at least one estimated operating parameter. The disturbance rejection controller refines the at least one estimated operating parameter as a function of the error amount. The auxiliary control torque signal is generated to minimize the error amount.
