Guaranteed cost control and bounded-input for the uncertain networked control system

This paper focus on the uncertain networked control system under the consideration of some problems in the systems and some uncertain factors affecting the systems stability based on guaranteed cost control.The sufficient condition for the uncertain networked control system which is subject to the closed-loop system asymptotic stability and H∞performance is mainly derived based on the Lyapunov stability theory and Linear Matrix Inequality（LMI）.The corresponding control strategy and guaranteed cost feedback controller which can optimalize the system performance are given at last.
