调整传输频率到谐振点附近是无线电能传输中提高传输效率的关键，而谐振点随着发送设备与接受设备间距的变化及元件参数的改变而变化。针对这一问题，文中提出一种利用模糊控制方法寻找传输效率最优点的思路，并针对实际系统对模糊控制器进行了设计，使用Matlab工具对所设计的自寻优控制方法进行了仿真。结果表明，利用这种模糊控制方法能较快地将系统传输频率调整到谐振点附近，以使传输效率达到最优。

To adjust the transmission frequency to the nearby of resonance point is very critical in the wireless power transmission system. But the resonance point changes due to the varies of the transmitting distance and the component parameters. To solve this problem, a fuzzy control method for finding the maximum transmission efficiency point is proposed in this paper. And a fuzzy control-ler for the actual system has been designed. The self-optimizing control system is simulated in MAT-LAB platform . The simulation results show that the use of this control method can adjust the transmis-sion frequency to the around of resonance quickly for reaching the optimal transmission performance.
