摘要

研究了存在数据包丢失的网络控制系统的镇定问题。给出了具有丢包的ncs的稳定性和镇定性的充分条件。这项工作的新颖之处在于，具有任意但有限数据包丢失的ncs被建模为切换的线性系统，这使我们能够将切换系统的结果应用于这种ncs的分析和综合。丢包的允许上界可以用一组线性矩阵不等式(lmi)来确定，这保证了ncs的稳定性。稳定控制器(通过状态反馈和静态输出反馈)可以通过求解一组lmi来构造。对于具有收敛速率约束的NCS，也得到了类似的结果。算例说明了所提方法的有效性

Stabilization of networked control systems with data packet dropout via switched system approach

The problem of stabilization of networked control systems (NCSs) with data packet dropout is studied. Sufficient conditions are presented on the stability and stabilization of the NCSs with packet dropout. The novelty of this work lies in that NCSs with arbitrary but finite data packet dropout are modelled as switched linear systems, and this enables us to apply the result of switched systems to the analysis and synthesis of such NCSs. The admissible upper bound of the dropped packets can be determined by a set of linear matrix inequalities (LMIs) which guarantee the stability of the NCSs. Stabilizing controllers (via state feedback and static output feedback) can be constructed by solving a set of LMIs. Also, for an NCS with a convergence rate constraint, similar results are obtained. Examples are worked out to illustrate the effectiveness of the proposed method
