摘要：

Concerning the problem of controller design for a class of networked cascade control systems, based on the stability analysis, the reliable primary and secondary controllers are designed, an event-triggered scheme is introduced to reduce the unnecessary waste of the limited network bandwidth resources for the first time. Firstly, considering the effect of the transmission delay, a model with the event-triggering scheme is constructed. Then, by using the Lyapunov stability theory and linear matrix inequality technique, some sufficient conditions of stability are proposed and the corresponding primary and secondary controllers are also obtained for the systems. Finally, a simulation example is given to illustrate the effectiveness of the proposed method. That is to say, with the introduction of the event-triggered scheme, the designed primary and secondary controllers make the interval of signal transmission larger under the premise of system stability, thus the congestion of network is reduced and the effective utilization of network bandwidth is improved. © 2018, Editorial Office of Control and Decision.
