The Improvement of Fastness for a Kind of Uncertain Networked Systems Based on the Stripping Principle and Optimal Control

In this paper, based on using the stripping principle and optimal control, we consider the improvement of fastness for a kind of uncertain networked systems which are composed of some heteromorphic subsystems. The method can be summarized as follows. Facing the complex networked structure and the unavoidable uncertainties or disturbances, we use the integral feedback with a variable gain for each of the subsystems to remove or eliminate the interconnected parts, uncertainties and disturbances. So we turn the control problem of networked systems into that of decentralized control. And then we use optimal control for the subsystems respectively. Then the fastness of the networked systems can be improved. The theoretical analysis and simulation result are given to indicate the effectiveness of the proposed approach.
