The invention discloses a voltage stabilization control method of a dynamic wireless charging system based on adaptive output adjustment. The method comprises the following two steps of: 1, constructing an external system by using an output regulation theory according to the interference on an energy receiving end Buck type DC-DC converter of the dynamic wireless charging system of the electric vehicle and a reference voltage needing to be tracked, and converting a voltage stabilization control problem of the dynamic wireless charging system of the electric vehicle into an output regulation problem; secondly, an internal model controller is designed based on the built mathematical model of the external system and the DC-DC converter, meanwhile, an adaptive control theory is introduced, internal model parameters are estimated, and an adaptive internal model controller is obtained; according to the method, the uncertainty of circuit parameters in the dynamic wireless charging system of the electric vehicle can be processed, the uncertainty of parameters of the internal model controller caused by unknown vehicle speed can also be processed, and finally, the influence of large-range energy disturbance caused by movement of the electric vehicle on the dynamic wireless charging system is inhibited; the method has a practical application prospect.

    本发明公开了一种基于自适应输出调节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,利用输出调节理论,针对电动汽车动态无线充电系统能量接收端Buck型DC‑DC变换器受到的干扰和需要跟踪的参考电压,构建外系统,将电动汽车动态无线充电系统的稳压控制问题转化为输出调节问题;第二,基于构建的外系统和DC‑DC变换器的数学模型设计内模控制器,同时引入自适应控制理论,对内模参数进行估计,得到自适应内模控制器。本发明不仅可以处理电动汽车动态无线充电系统内部的电路参数不确定性,还可以处理由车速未知带来的内模控制器参数的不确定性,最终抑制由电动汽车移动引起的大范围能量扰动对于动态无线充电系统的影响,具有实用的应用前景。
