线性不确定大系统的分散变结构控制

Decentralized Variable Stracture Control of Uncertain Linear Large scale Systems

本文研究了具有参数摄动、关联影响和外界干扰等不确定因素影响的线性大系统的分散控制问题。在假设系统不确定性有界且满足一定匹配条件的前提下 ,给出了系统的一种分散变结构控制算法 ,实现了大系统的全局渐近稳定。该控制律设计简单 ,并保证了闭环系统较好的动态性能和较强的鲁棒性。

This paper investigates the decentralized asymptotic stablization problem for a class of Uncertain Linear large scale systems with parameteric perturbation,extraous disturbance and interconnections.Because of the assumption of uncertainty bounded and matched,a new simple roubst decentralized sliding mode controller for each subsystems is proposed to assure the global asymptotic stability of the uncertain linear large scale systems.
