摘要
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．
In this paper, we present sufficient conditions for existence of decentralized robust controller and tracking controller for large scale uncertain systems. The uncertainty is value bounded and can be dissatisfied with so called matching conditions. With this representation, we give robust decentralized control laws for two classes of uncertain interconnected systems. In the former, the uncertainties may be time varying, and the controlled system can converge exponentially with a prescribed rate under the decentralized robust controller. In the latter, the uncertainties are time invariant, and we give a robust tracking controller which guarantees the controlled system to approach the reference input exponentially.
