The stability control for a kind of uncertain networked systems by using a new separation principle

In this paper, we consider a new synthesis method to the stability control for a kind of uncertain networked systems which are composed of some heteromorphic subsystems. Here we call it a new separation principle. The method can be summarized as follows. Facing the complex networked structure and the unavoidable disturbances, we use integral feedbacks with variable gains to remove or eliminate the interconnected parts and disturbances. So we turn the problem of networked control into that of decentralized control. And then we use decentralized control for the subsystems respectively. Through choosing the proper state feedbacks, the stability control can be implemented. The theoretical analysis and simulation results are given to indicate the effectiveness of the proposed approach.
