The invention discloses an electric vehicle wireless charging control system and method based on a composite anti-interference controller. Through data measured by the sensor, voltage control of the wireless charging system of the electric vehicle without complex mathematical modeling analysis is realized. The core composition part of the invention comprises a model-free expansion state observer module, a non-smooth dynamic sliding mode surface module, a composite anti-interference control law module and a wireless charging system. Compared with an existing wireless charging control system of the electric vehicle, the wireless charging control system of the electric vehicle is controlled by introducing the general disturbance model and the expansion state observer module, only single sensor data is depended on, and a complex mathematical model does not need to be constructed in advance. Meanwhile, state feedback information and a feed-forward compensation strategy are combined, so that the accuracy and setting performance of the output voltage of the system are remarkably improved, the cost of initial implementation and later maintenance is reduced, and the stability of the control system is further enhanced.
