Abstract
An improved extended Kalman filter algorithm based on permanent magnet linear synchronous motor (PMLSM) is presented in this paper. This algorithm uses the current time estimate to linearize the system state transition matrix. The results show that the dual Extended Kalman Filter has better estimation accuracy than the traditional Extended Kalman Filter.
