摘要
研究基于输出反馈的一类新的大型互联非线性不确定系统的鲁棒全局指数稳定问题,通过构造每个子系统收敛的状态观测器,并对观测器的状态作线性变换,得到鲁棒分散输出反馈控制器.当该反馈控制律作用于该系统时,闭环系统是全局指数稳定的.
The problem of robust global exponential stabilization for a class of new largescale interconnected nonlinear systems with uncertainties via output feedback is studied. The decentralized output feedback controllers are obtained by designing a convergent state observer of each subsystem and using the linear transformation of the states of each observer. When the feedback control laws are applied to the systems, the closed-loop systems are global exponential stable.
