Abstract:
Considering the uncertain network induced delay,using state augmentation method,a discrete linear system model with uncertainties of networked control system is established under the assumption of time-driven sensor,event-driven actuator and controller,single data-packet transmission and transmission delay that is less than sample interval.The nominal model is proved controllable.Using Lyapunov approach,the sufficient condition of asymptotic stability is proposed,and parametric design method of state feedback control law is given based on the feasible solution of matrix inequality.Simulation results verifies the validity of the proposed method.
