In this paper, we study the parameters identification problem of Permanent Magnet Synchronous Motor (PMSM) in steady state. First, the controlled auto-regressive (CAR) model of PMSM is established. Secondly, based on the obtained CAR model, an improved stochastic gradient algorithm is proposed to identify the electrical parameters of PMSM. By introducing a tuning parameter in the presented algorithm, the current estimation for the unknown PMSM parameters is updated by using the information not only in the current step but also in the previous step. In addition, a convergence result is provided for the developed algorithm. Finally, an example is given to show the advantage of the proposed algorithm for the parameters identification of PMSM.
