中文摘要: 磁耦合谐振无线电能传输系统的负载和谐振参数会因为受到外界环境的影响而发生变化, 系统工作频率发生随机漂移, 导致模型参数存在不确定性. 针对参数不确定下的输出鲁棒控制问题, 本文基于H∞控制理论, 应用Matlab鲁棒控制工具箱设计H∞控制器, 并基于结构奇异值法分析了闭环系统的鲁棒稳定性与鲁棒性能. 结果表明, 在H∞控制器的作用下, 实现了闭环摄动系统的输出鲁棒控制, 并为此类高阶非线性不确定闭环系统提供了一种通用的控制器设计方法.
Abstract:The loads and resonant parameters of magnetically coupled resonant wireless power transfer system are changed due to the external environment, then the operating frequency will be random drift and resulting in model parameter uncertainty. To solve the problem of robust output control with uncertain parameters, the H∞ controller is designed by making use of Robust Control Toolbox of Matlab based on H∞ control theory in this article. We use the method of structured singular value to analysis robust stability and robust performance for the closed-loop system. The results show that by applying H∞ controller the closed loop perturbation system realizes robust output control and the controller is designed to provide a general method for such high-order nonlinear uncertain closed-loop perturbation systems.
