The invention discloses a voltage control method and system for a dynamic wireless charging system of an electric vehicle. The single voltage sensor is adopted to collect the actual output voltage, and based on the actual output voltage, the nonlinear tracking differentiator, the nonlinear single sensor expansion state observer and the anti-interference state error feedback controller are introduced, so that accurate control over the dynamic wireless charging system of the electric vehicle is successfully achieved. The dynamic response speed and the anti-interference performance of the system are remarkably improved, meanwhile, the implementation cost is greatly reduced, and the stability and the robustness of the control system are further enhanced. According to the method, a feasible solution is provided for the high-efficiency performance of the dynamic wireless charging system of the electric vehicle, the development and application of the wireless charging technology are promoted, and the method is expected to generate far-reaching influence in the field of electric vehicle charging in the future.
