Aiming at a series of problems caused by the position sensor required by the salient pole permanent magnet synchronous motor (IPMSM) control system, a high-frequency square wave injection sensorless control algorithm suitable for IPMSM low-speed control system is realized in this paper. Compared with other sensorless control algorithms, its advantages are that it avoids the system delay caused by the filter by injecting high-frequency square wave signal, and has good stability and robustness at low speed. The feasibility and effectiveness of this method are verified by simulation. At the same time, it shows that the high-frequency square wave injection method has good accuracy of rotor position estimation, and can ensure the good stability and dynamic performance of the whole drive system. Through the simulation results, better injection voltage amplitude is selected to reduce the electromagnetic interference and electromagnetic noise caused by high-frequency square wave injection signal.
