Event-Triggered Control for a Class of Discrete-Time Networked Cascade Control Systems With State Delay

We mainly study the controller design problem of discrete network cascade control systems (NCCSs) with state delay and event-triggered control are studied firstly in this paper. For the reason that use network bandwidth resources effectively, a delayed event-triggered mechanism is introduced into the system with time delay. Firstly, Considering the influence of network delay and event-triggered control, and on account of the above conditions, the NCCS model with state delay is established. After that, We can construct a suitable Lyapunov function and provide sufficient conditions of system stability. On this basis, the co-design method of the four event generator parameters and two gain of proportional (P) controllers. Finally, based on the actual needs of industry, a Matlab simulation example of NCCS based event-triggered control in a thermal power plant is given to show the availability of this way, which shows that this method can save network bandwidth resources.
