| 中文摘要: |
| 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LMI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． |
| 英文摘要: |
| 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. |
