具有时延和丢包的不确定性NCS的稳定性

研究了同时具有网络时延和数据丢包的不确定网络化控制系统的稳定性.将数据丢失看成一种特殊的时延,利用动态反馈控制器设计提高系统的动态性能,得到了总时滞(包括传感器与控制器之间的时滞,控制器与执行器之间的时滞)的表达式,建立了不确定网络化控制系统模型.通过构造李亚普诺夫函数,采用线性矩阵不等式技巧,给出了系统稳定的判定定理.仿真结果表明了该方法的有效性.

Stability of Uncertainty NCS with Time-delay and Data Packet Dropout

This paper studies the stability of the uncertain networked control systems with network-induced delays and data packet dropout.The packet dropout is considered as a special kind of delay.A dynamic feedback controller is introduced to stabilize the networked control systems and improve their dynamic performance.The expression of total network-induced delay including the sensor-to-controller delay and the controller-to-actuator delay is given,and the networked control system model is established.The theorem ...
