针对短时延的多包传输网络控制系统,研究了数据包传输次序不确定情况下系统的建模及控制问题.引入了补偿器来补偿多包传输过程中部分数据丢失对系统的影响,同时考虑不确定短时延的影响,将其建模成一类具有参数不确定的离散随机切换系统,并对系统的稳定性进行了分析.仿真结果证明了该方法的有效性.
For the networked control systems with multi-packet transmission and uncertain short time delay, system modeling and control problem are studied in the case of uncertain packet transmission sequence. A compensator is introduced to compensate the effect of part of data dropout in the process of multi-packet transmission. Considering the effect of uncertain short time delay, the NCS is modeled as a discrete stochastic switching system with uncertainty,the asymptotic stability of the system is also analyzed. Simulation result shows the validity of the method.
