Abstract: As for the influence of the long network-induced delay on the system stability,by equaling the uncertain delay to the uncertainties of system parameters,a discrete system model with uncertain parameters of WINCS is established.Based on this model,the asymptotically stable conditions for a closed-loop wireless networked control system are proposedby using Lyapunov function method,and also a state feedback controller design method is given in terms of linear matrix inequality(LMI).Finally,the proposed model and the control method are proved to be effective through a numerical emulation.
