The invention discloses a voltage stabilization control method of a dynamic wireless charging system based on adaptive loop compensation. The method comprises the following two steps: 1, designing a feedback controller conforming to frequency domain design parameters according to expected phase margin and crossing frequency; and 2, according to the designed feedback controller, adaptive iteration is carried out on parameters of the feedback controller by utilizing a reference model adaptive control theory, so that the feedback controller with better performance is obtained. The self-adaptive control algorithm is introduced, compared with a conventional lead-lag loop compensation feedback controller, the electric vehicle can have satisfactory anti-interference performance when static wireless charging is conducted, large-range voltage disturbance caused by movement of the electric vehicle in the dynamic wireless charging process can be restrained, practicability is higher, and the method is suitable for popularization and application. And the application range is wider.
本发明公开了一种基于自适应环路补偿的动态无线充电系统的稳压控制方法。本发明分为两个步骤,第一,根据期望的相位裕度和穿越频率,设计符合频域设计参数的反馈控制器;第二,根据上述设计的反馈控制器,利用参考模型自适应控制理论,对反馈控制器参数进行自适应迭代从而获得具有更佳性能的反馈控制器。本发明引入了自适应控制算法,相比常规的超前滞后环路补偿反馈控制器,不仅可以令电动汽车在进行静态无线充电时有令人满意的抗干扰性能,还可以抑制在动态无线充电过程中由于电动汽车移动引起的大范围电压扰动,实用性更强,应用范围更广。
