摘要

无线充电系统的输出特性复杂，其自身参数的时变性和不确定性以及外界的扰动等都会导致输出特性发生显著变化，给无线充电系统输出控制造成很大困难。针对电动汽车无线充电系统的输出控制问题，首先利用广义状态空间平均法对系统进行了建模，得到了全电路和简化电路的状态空间方程。然后，基于系统的负载和互感参数摄动，在状态空间模型上建立了无线充电控制模型，设计了鲁棒H∞控制器，并进行了系统的稳定性分析。最后，通过仿真和试验验证了所提闭环控制系统的稳定性。

Abstract

Complex output characteristics of wireless charging system will lead to significant changes in output characteristics due to time-varying and uncertain parameters

as well as external disturbances

which is very difficult to control the output of the wireless charging system. Aiming at the control problem of output for wireless charging system

firstly

the generalized state space averaging method is used to model the system and the state space equations of the whole circuit and the simplified circuit are obtained. Then

based on parameters perturbation of load and mutual inductance

the model is established according to the state space model

A robust H∞controller is designed and the stability analysis of the system is also carried out. Finally

the stability of the closed-loop control system is verified by simulation and experiments.
