The interior permanent magnet synchronous motor (IPMSM for short) has been widely used in many fields, such as rail transport, robot and even the aerospace. The research on the vector control strategy of permanent magnet synchronous motor has attracted much attention. The traditional vector control strategy needs to obtain the position information of the rotor through the position sensor. However, the position sensor has a series of shortcomings such as high cost and poor stability. Therefore, the research on the sensorless sensor has gained more and more attention. In the front research, we have put forward many different kinds of methods on sensorless control, but there are some obvious disadvantages. This paper introduces a sensorless control method in the full speed range. The motor is started by I/f control. When the motor is in the middle and high-speed stage, this paper uses the method based on disturbance observer to estimate the rotor position, and it achieved good results.
