针对同时存在网络诱导时延和丢包的网络控制系统，提出了一种新的切换线性系统模型。给出了闭环网络控制系统指数稳定的一个充分条件，建立了丢包率与网络控制系统稳定性之间的定量关系。利用增广技术给出了状态反馈镇定控制器的设计方法。最后通过一个算例验证了该方法的有效性。(C)2008爱思唯尔有限公司保留所有权利。
A new switched linear system model is proposed to describe the networked control system (NCS) with both network-induced delay and packet-dropout. A sufficient condition is derived for the exponential stability of the closed-loop NCS, and the obtained condition establishes the quantitative relation between the packet-dropout rate and the stability of the NCS. Design procedures for the state feedback stabilising controllers are also presented by using the augmenting technique. An illustrative example is provided to demonstrate the effectiveness of the proposed method. (C) 2008 Elsevier Ltd. All rights reserved.
