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. The Lurie system is regarded as the controlled object to study its guaranteed cost control in the network environment.Under the condition of random network induced delay and data packet loss, an uncertain Lurie networked control system model is established. By using Lyapunov The methods are given respectively for the design of guaranteed cost controller of Lurie networked control system with the existence of structural uncertainty and bounded uncertainty of norm. The results are given in the form of linear matrix inequalities for numerical solution Finally, a numerical example is given to illustrate the feasibility and effectiveness of the proposed method.
