摘要
基于LMI方法,在考虑存在外部扰动的情况下,给出了时变不确定性关联时滞大系统的分散控制器的设计方法.通过构造分散控制律,使得闭环系统具有一定的鲁棒稳定性.由求解一线性矩阵不等式组(LMIs)可获得满足设计要求的控制器.其算例表明了该方法的有效性.参10.
The problem of decentralized robust H_∞ control for uncertain interconnected systems.With time-delay is studied in the paper. In disturbances,a method for the design of corresponding controllers is given in the large-scale uncertain interconnected systems with time-delay.The controller can not only stabilize the controlled system,but also guarantee H_∞ properties which the decentralized controlling laws are built.The decentralized controller Can be obtained by solving a set of LMIS.A numerical example illustrates the effectiveness of the method.10refs.
