摘要: 研究反标架规范化控制器的鲁棒性能问题,以结构奇异值SSV(Structured Singular Value)为工具,将对象、系统开环传递函数和控制器以奇异值分解形式参数化,就方向性 和耦合性引起的困难分别进行了讨论,得到了使系统保持鲁棒性能所需要的关于开环传递函 数和控制器参数的充分条件,为反标架规范化结构鲁棒控制器设计提供了理论依据.Abstract: The robust performance of reversed-frame normalized controller is studied. Taking SSV (Structured Singular Value) as measure, and describing the plant, the open-loop transfer function and the controller in the form of singular value decomposition, some sufficient conditions guaranteeing robust performance are drawn about the parameters of the open-loop transfer function and the controller as the result of directionality and coupling analyses. This forms the theoretical basis for the design of robust controller with reversed-frame normalized structure.
