Packet dropout is one of the key issues which degrade performances of Internet-based Control System(ICS). An integrated strategy composed of active part and passive part to solve this problem is proposed in this paper. In the active part, the priority of control packets in ICS can be improved through differentiated services which decrease probability of control packet dropout. While in the passive part, a data packet dropout compensator is established to reduce the negative influence of packet dropout. The sufficient conditions for stabilizing the new result model are derived in the form of linear matrix inequalities (LMI). At last, the solvability and effectiveness of the results is evaluated using NS2.
