Title Research on event-triggered control and simulation for network control system
Abstract
With the development of network control and communication technology , more and more network transmission mode is applied to control field, thus developing the network control system (NCS). It can reduce unnecessary bandwidth during information transmission by using triggering mechanism and improve the overall system performance of network control system. For resource constrained network control system with random time delay,this paper puts forward a method based on event driven network control system(NCS) . This method add the output signal and the control signal of the delay system into the augmented system state variables. At the same time, with the event-triggered method, we can finally achieve the discrete model of the system. Based on the Lyapunov stability theorem,it solves out the controller parameters to satisfy the performance of system. Finally,the article will give the simulation results by using truetime platform and the analysis of the network control system performance, as well as to verify the feasibility of the designed algorithm.
