摘要
A system for detecting offset error in a power steering system comprises a programmable high pass filter module configured to filter a final voltage command and generate a filtered final voltage command that includes the sinusoidal component, a gain and phase compensation module configured to perform a gain compensation and a phase compensation on the filtered final voltage command to generate a compensated final voltage command; and an error detection module configured to determine an offset of the compensated final voltage command in a stator reference frame.
