The synchronous mode is widely used in the start-up of a position sensorless PMSM drive system. However, the shock in speed and current may occur when the control mode is changed to the position sensorless control mode for a wide-range load. In this paper, a start-up method for a PMSM with position sensorless control is presented. To reduce the shock in speed and current when the control mode is changed, a method to adjust the vector angle of current reference in the synchronous mode is proposed. Using the method, the position error between the control axis and rotor axis can be reduced before the control mode is changed, and all of the PI controllers can be initialized properly. The effectiveness of the proposed method is verified by simulation and experimental results.
