针对一类含有不确定参数被控对象的网络化控制系统（NCS ），研究了网络中存在时延与丢包情况下的鲁棒 H∞保性能控制问题。通过Lyapunov-Krasovskii泛函和Jensen不等式，推导出闭环NCS鲁棒渐近稳定的充分条件。与已有文献相比，该充分条件可以转换为具有较少决策变量的LM I形式。给出了NCS鲁棒 H∞保性能控制律的优化设计算法。最后通过数值实例验证了算法的有效性。

Robust H∞ guaranteed cost control problem for a class of uncertain networked control systems (NCS) with network-induced delay and packet dropout is investigated .A sufficient condition for robust asymptotic stability of the closed-loop NCS is derived by using Lyapunov-Krasovskii functional and Jensen′s inequality ,which can be expressed as a linear matrix inequality (LMI) with fewer decision variables than those in existing literatures .An algorithm for optimization design of the robust H∞ guaranteed cost control law is also presented .Numerical examples are given finally to illustrate the effectiveness of the algorithm .
