Abstract :
For the networked control system with time-varying bounded sampling period and time delay, it is modeled as a class of discrete dynamic interval system. Based on this, the H∞ robust control problem of the system is studied. The asymptotic stability condition of the system is obtained in terms of linear matrix inequalities(LMIs) and a state feedback H∞ controller is also proposed. Simulation result shows the validity of the method.
