The invention discloses an output voltage control method for a dynamic wireless charging system of an electric vehicle. A DC-DC circuit of an energy transmission transmitting end is designed, a linear active-disturbance-rejection controller and a hybrid controller are introduced, the linear active-disturbance-rejection controller observes state variables of the DC-DC circuit and estimated values of disturbance through an extended state observer, a linear state feedback control law forms a first control quantity, a disturbance compensation link outputs a second control quantity, and the DC-DC circuit is connected with the hybrid controller. The constant input voltage of the full-bridge inverter circuit is ensured; the hybrid controller outputs the switching frequency and the phase shift angle to adjust the stability of the load output voltage and the wide adjustment range of the system voltage gain. According to the method, the constant-voltage regulation performance and the anti-interference performance of the system are remarkably improved, meanwhile, the implementation cost of adjusting system elements is reduced, the stability and robustness of the system are further enhanced, and an effective solution is provided for stable operation of the dynamic wireless charging system of the electric vehicle.
