Aiming at the encoder fault of the three-phase permanent magnet synchronous motor control system, a modified eXogenous Kalman Filter (MXKF) is proposed. When there are errors in the initial state of the estimator, MXKF performs well while extended Kalman Filter leads to an unstable state of the syst...
