摘　　要：基于正则、无脉冲的奇异被控对象,研究了同时具有时延和数据包丢失的动态输出反馈网络控制系统的建模和稳定性问题。当时延不大于一个采样周期、数据包丢失率一定时,将动态输出反馈网络控制系统建模为数据包丢失率约束的异步动态切换系统,利用切换系统和线性矩阵不等式方法,推导出数据包丢失率约束的系统指数稳定的充分条件,并且给出了系统指数稳定的指数衰减率以及最大容许数据包丢失率。仿真实验说明分析方法和研究结果是有效可行的。Based on a regular and impulse-free singular controlled plant,the problem of exponential stability and modeling of dynamic output feedback networked control systems with network-induce delay and data dropout is studied.Considering network-induce delay less than or equal to one sampling period and certain data packet dropout,the dynamic output feedback networked control systems are modeled as an asynchronous dynamical-switched systems constrained by packet dropout rate.By using switched systems and linear matrix inequality approach,the sufficient conditions of exponential stability for the NCS are derived,and the exponential damping decrement and the maximum allowable dropout rate for stability are presented.A simulation example shows that the analysis method and result are valid and feasible.
