H-Infinity Robust Optimal Control Of Variable Period Ncs With Uncertain Delay And Packet Loss

For a class of network control system with uncertain time delay, packet loss, variable sampling period and the external disturbance. Using LMI and Lyapunov method to research robust H-infinity optimal control based on dynamic output feedback. Giving sufficient conditions for the system's progressive stability and the existence of dynamic output feedback controller. Finally, the design method of optimal H-infinity control rate is given by solving optimization problem, and using LMI toolbox to verify the effectiveness of the proposed method.
