| Abstract: | A newly designed sliding mode observer to estimate the position and speed of a surface permanent synchronous motor(SPMSM) is presented,and a position sensorless PMSM vector control system is constructed.An improved phase-compensation strategy is proposed to minimize the unwanted phase lag and forcast unknown paramter variation.To show the validity of the proposed control scheme,simulations are carried out and the results are analysed at last. |
