摘要
以不确定Lurie系统作为被控对象,研究其在网络环境下的保性能控制问题.在同时考虑随机网络诱导时延和数据丢包的情况下,建立不确定Lurie网络化控制系统模型;利用Lyapunov方法分别给出了存在结构不确定性和范数有界的不确定性时,Lurie网络化控制系统保性能控制器的设计方法.所得结果是以线性矩阵不等式的形式给出的,便于数值求解.最后以数值实例说明了所提出方法的可行性和有效性.
Guaranteed cost control problem of networked control systems with the controlled plant being uncertain Lurie systems is studied. With the consideration of the random network-induced delay and data dropout,a model of Lurie networked control systems is established. And a simple design approach to guaranteed cost controller of Lurie networked control systems with the structured uncertainties and norm-bounded uncertainties is proposed by using Lyapunov method. Moreover, the obtained results are given in terms of linear matrix inequalities, which can be efficiently solved via standard numerical software. Finally, a numerical example illustrates the feasibility and effectiveness of the proposed approach.
