| 摘 要： | 将数据包丢失看成一种特殊的时延,研究了同时具有网络诱导时延和数据包丢失的网络化控制系统的稳定性问题.采用动态反馈控制器稳定系统并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,建立了网络化控制系统模型,证明了系统的稳定性判定定理.仿真结果表明了该方法的有效性.

| Abstract: | Stability of the networked control systems with network-induced delays and packet losses is investigated by considering a packet loss as a special kind of delay.A dynamic feedback controller was 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 presented,the networked control system model established,and the stability theorem proved.The simulation results also illustrated the effectiveness of the proposed approach. |
