Abstract

Technical solutions are described for facilitating a steering system to determine a motor velocity estimate for a motor of the steering system. For example, the steering system may include a state observer module that computes a base motor velocity estimate of the motor based on a plant model of the steering system. The steering system may further include a delay compensation module that computes a delay compensated velocity estimate based on the base motor velocity estimate and an acceleration of the motor. The steering system may further include a standstill detection module that modifies the delay compensated velocity estimate in response to a handwheel of the steering system being in standstill mode.
