Abstract
Systems and methods for compensating for a current measurement offset error in a permanent magnet synchronous motor (PMSM) drive are disclosed. The systems and methods include reading an output voltage command signal, extracting a signature of a current measurement offset error from the output voltage command signal, and compensating, based on the signature, for the current measurement offset error in a closed-loop using a feedback path.
