H∞ stabilization criterion based on free-weighting matrices for MIMO networked control systems

This paper investigates H∞ stabilization criterion for uncertain MIMO networked control system with disturbance, where its network transmission is connected with network-induced delay and packet dropout both sensor-to-controller and controller-to-actuator. In order to obtain much less conservative results, the criterion is analyzed by using 2nd Lyapunov stability theory combined with free-weighting matrices techniques. And the robust controller is formulated in the form of a matrix inequality, of which a feasible solution can be obtained by solving a minimization problem in terms of linear matrix inequalities.
