The event-based \(H_{\infty }\) control problem is researched for networked control systems subject to saturation constraints. In consideration of event-triggered mechanism and saturation constraints concurrently, the networked control system is modeled as a nonlinear system. By using Lyapunov-functional method and the linear matrix inequality techniques, the mean square stable criteria and \(H_{\infty }\) controller has been got for the controlled system with suitable event-driven matrix. A numerical example is given to illustrate the feasibility of the control approach in the paper.

The event-based \(H_\infty \) control problem of the networked control system is studied, which is under the constraint of stochastic actuators nonlinearity. Under event-triggered scheme and stochastic actuator nonlinearity restricted condition, a closed-loop system is constructed as a event-based nonlinear control system. Based on Lyapunov-Krasovskii function method and the stochastic analysis technology, \(H_\infty \) sufficient conditions have gained in the form of LMIs. The controller and the event-based weighted matrix are designed simultaneously. A simulation example is given to show the feasibility of the control method in this paper.
