一类大型互联非线性系统的鲁棒分散输出反馈控制

Robust decentralized output feedback control for a class of large-scale interconnected nonlinear systems

对带有界扰动的一类大型互联非线性系统进行了分散输出反馈控制设计。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。当输出反馈控制律作用于该系统时,无扰动的闭环系统是渐近稳定的,当扰动较小时,系统的状态能够收敛到原点的一个小邻域内。

This paper designed a decentralized output feedback control for a class of large-scale interconnected nonlinear systems with bounded disturbances.The robust decentralized output feedback controllers were obtained by designing a convergent state observer of each subsystem and using the linear transformation of the states of each observer.When the output feedback control laws are applied to the systems,the closed-loop systems without disturbances are asymptotically stable and the states of the systems can converge to a small region of the origin when disturbances are small.
