Abstract
A control system for a power steering system includes an error module that generates an error signal based on a difference of an estimated output vector and an output vector, a scaling module that calculates a feedback correction signal based on the error signal and an observer gain value, an extended state vector estimation module that determines an extended state vector estimate based on the feedback correction signal and a motor torque command, and a gain module that applies a gain to the extended state vector estimate to generate an estimated driver torque signal, the estimated driver torque signal is applied in control of the power steering system.
