一类不确定线性组合系统的输出跟踪

针对两种不确定线性组合系统提出了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，对于第一种系统，其不确定项可以是时变的，其受控系统以任意给定的收敛率指数渐近稳定；第二种系统中的不确定项是时不变的，文中给出了的鲁棒跟踪器可使受控系统渐近跟踪给定的参考输入。

Output Tracking for Linear Uncertain Interconnected Systems

Sufficient conditions for existence of decentralized robust controller and tracking controller are presented for large scale uncertain systems. The uncertainties have values bounded without satisfying so called matching conditions. In the first case,the uncertainties may be time varying,and the controlled system can converge exponentially with a prescribed rate. In the second case,where the uncertainties are time invariant,a robust tracking controller is proposed to ensure the controlled system to approach the reference input exponentially.
