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本文方法的有效性。 |
英文摘要: |
This paper is concerned with the H∞ guaranteed cost control problem for a class of uncertain networked control systems (NCSs) with network-induced delay and and packet dropout. A sufficient condition for asymptotic stablility of the NCS is derived by using Lyapunov-Krasovskii functional and the Jensen’s inequality, which can be expressed as a LMI with fewer decision variables than existing literatures.A 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 method. |
