The invention discloses an electric vehicle wireless charging system control method based on a self-adaptive voltage filter. According to the invention, the adaptive filter is introduced, so that the system voltage is accurately filtered and controlled without an additional sensor. Furthermore, an input gain online identification and self-adaptive filter module is introduced, and only single sensor data is used, so that the output voltage regulation of the dynamic wireless charging system is realized. Therefore, according to the method provided by the invention, the precision and the setting performance of the voltage are remarkably improved, the initial implementation cost and the later maintenance cost of the system are reduced, and the stability of the control system is greatly enhanced.

    本发明公开了一种基于自适应电压滤波器的电动汽车无线充电系统控制方法。本发明通过引入自适应滤波器,实现了在无需额外传感器的情况下对系统电压进行精确滤波和控制。进一步地,本发明通过引入输入增益在线辨识和自适应滤波器模块,仅使用单一传感器数据,实现了动态无线充电系统的输出电压调节。因此,本发明提出的方法显著提升了电压的精度和整定性能,降低了系统初始实施成本和后期维护成本,极大增强了控制系统的稳定性。
