Method and device for detecting position of rotor of permanent magnet synchronous motor, and medium

The invention discloses a method and a device for detecting the position of a rotor of a permanent magnet synchronous motor, and a computer readable storage medium, and the method comprises the steps: obtaining a position estimation value of the rotor of the motor, predicted values of components of current on a d-axis and a q-axis, and sampling current of the motor; according to the method, a position sensor is not required to be used, the reliability of the system is improved, the reliability of the system is improved, the reliability of the system is improved, and the reliability of the system is improved. In addition, the method is not affected by the environment, the debugging workload is small, other measures do not need to be additionally added, the motor can be started and run from a static state, high-precision detection of the position of the rotor at the full-speed section can be achieved, and the working efficiency of the permanent magnet synchronous motor is improved. 本申请公开了一种永磁同步电机转子位置的检测方法、装置及计算
