The invention discloses a self-adaptive voltage control method for a wireless electric energy transmission system of an electric vehicle. Comprising the steps that a self-adaptive model prediction controller is constructed in combination with an RBF neural network, and the self-adaptive model prediction controller outputs a control quantity at the moment k and acts on a wireless electric energy transmission system of the electric vehicle; the adaptive model prediction controller performs adaptive adjustment of state deviation according to the k + 1 moment state quantity of the wireless electric energy transmission system of the electric vehicle and the fixed model reference system, outputs the next control quantity, acts on the wireless electric energy transmission system of the electric vehicle, continuously acquires the state quantity of the system and adjusts the control quantity; therefore, online self-adaptive control of the wireless electric energy transmission system of the electric vehicle is completed. According to the invention, accurate control of the dynamic wireless power transmission system of the electric vehicle is realized, the dynamic response performance and the anti-interference performance of the system are obviously improved, the model can be dynamically adjusted especially for various external interferences of the system, and the stability of the control system is enhanced.
