Research on Modeling and Stability Analyzing of Networked Control Systems with Parameter Uncertainties and Long Time Delay
Considering the uncertain long time-delay of networked control systems with parameter uncertainties,the modeling problem was discussed and analyzed firstly.Suppose sensor nodes of networked control system were time.driven,actuators and the controller were event-driven,the sampled data of sensors were lumped together into a single data packet.and the transmission delay was more than one sampling period and parameter uncertainties existed in the system.the networked coutrol system with parameter uncertainties and Iong time delay Was modeled as an uncertain discrete Iinear system with long time-delay.And then based on Lyapunov functional approach.Sufficient conditions of asymptotic stability of closed-loop systems were given,and the state feedback controller was obtained based on the feasible solution of the Iinear matrix inequalities.The simulation results verify that the method is valid for the uncertain long time-delay problem of networked control systems with parameter uncertainties.
