Event Triggering Mechanism Of Network Control System With Transmission Delay And Packet Loss Coexisting

In this thesis,a network control system with transmission delay and packet loss was established in the absence of acknowledgement mechanism.In view of the limited communication resources in network control system,the combination of time trigger and event trigger was adopted.Firstly,the network control system with transmission delay and packet loss in sensor-controller channel was studied.Using the analysis method of the hybrid system,appropriate event triggering conditions were designed to ensure the stability and performance of the system.At the same time,a strict positive lower bound exists between two adjacent events,thereby avoiding the phenomenon of Zeno.Secondly,the network control system of the sensor-controller and the controller-actuator channel with transmission delay and packet loss was considered.Appropriate event triggering conditions were designed for the two channels,and the stability of the system was proved by using Lyapunov function method.Finally,a specific linear calculation example was given to verify the correctness of the conclusion.Meanwhile,the stability of system was verified by simulation.
