提出了不确定线性组合系统存在分散鲁棒反馈控制器和输出跟踪器的充分条件．系统中不确定项具有数值界，可不满足所谓的匹配条件．基于不确定项的数值界表达形式，本文针对两类不确定线性组合系统分别给出分散鲁棒控制律．对于第一类系统，其不确定项可以是时变的，在分散鲁棒反馈控制器作用下受控系统能以任意给定的收敛率指数渐近稳定；第二类系统中的不确定项是时不变的，本文给出其分散跟踪器，使受控系统可渐近跟踪给定的参考输入．
A sufficient condition for the existence of decentralized robust feedback controller and output tracker for uncertain linear systems is proposed. Uncertain items in the system have numerical bounds that may not satisfy the so-called matching condition. Based on the numerical boundary expression of uncertainties, this dissertation presents decentralized robust control laws for two types of uncertain linear systems. For the first type of system, the uncertainties can be time-varying, and the controlled system can be asymptotically stable with any given convergence rate index under the decentralized robust feedback controller. The uncertainties in the second type of system Is constant, this paper presents its decentralized tracker, which allows the controlled system to asymptotically track a given reference input.
