Abstract In order to solve the problem that the synchronous reluctance motor can not achieve self-starting and low speed operation under sensorless control based on sliding mode observer, the I-f method based self-staring control is studied in this paper. The single current closed-loop starting of the motor and the smooth switching from I-f control to sensorless control based on sliding mode observer are realized by using the torque-power angle self balancing characteristic of the motor. At the same time, the influence of the current drop rate on the switching process is analyzed. By using the variable slope method, the stability and rapidity of the switching process are guaranteed. Simulation results show that this method is effective and feasible for solving the above problems.
