摘要:

在时延、丢包、乱序的情况下,将Lurie网络化控制系统建模为一个多时滞的Lurie系统,利用添加自由权矩阵的方法给出时滞依赖的稳定性条件,并通过增加一等式约束将它转化为线性矩阵不等式表示的可解性问题,从而获得动态输出反馈控制律. 最后以两个仿真实例说明了该设计方法的可行性和有效性.

关键词: Lurie系统, 网络化控制系统, 动态输出反馈, 线性矩阵不等式, 非线性系统

Abstract:

Taking into consideration network-induced delay, data packet dropout and data packet disorder, the Lurie networked control system is modeled as a multiple delay Lurie system. A delay-dependent stability condition is established via free weighting matrices. Based on an equation constraint, it is transformed into a solvability problem described by linear matrix inequality. The dynamic output feedback control law is then presented. Two numerical examples show feasibility and effectiveness of the design method.

Key words: nonlinear system, Lurie system, networked control systems, dynamic output feedback, linear matrix inequality
