N2 - The parameters of the position observer do not match the actual parameters in the process of the sensorless control of the permanent magnet synchronous motor, which will lead to the decline of its control performance. Aiming at this problem, a method based on the online parameter identification for the sliding mode observer of permanent magnet synchronous motoris proposed. The parameters are identified by the affine projection algorithm and updated to the improved sliding mode observer in real time. The estimated back-EMF is calculated by the phase-locked loop to obtain the rotor position and speed. Simulation and experiments are set to verify the effectiveness of the method.
