The invention relates to a permanent magnet synchronous motor sliding mode anti-interference control method based on a compensation function observer, and belongs to the technical field of control engineering. As a complex nonlinear strong coupling system, a permanent magnet synchronous motor is easily influenced by external interference in operation, and traditional proportional-integral control is relatively weak in interference suppression capability, so that the robustness of the system is poor. Therefore, a sliding mode control strategy based on the observer is designed for the permanent magnet synchronous motor system.

And the designed observer has higher response speed and higher observation precision. According to the method provided by the invention, buffeting of the sliding mode controller is effectively weakened, and the anti-interference capability and the angular position tracking precision of the permanent magnet synchronous motor system are remarkably improved.
