Robust H∞output tracking control of uncertain networked control systems

摘要

This paper investigates a problem of robust output tracking control of networked control systems ( NCSs ) with network-induced delays , packet dropouts , parameter uncertainties and external dis-turbances.Firstly, an augmented model of time-delay system is proposed for networked tracking control systems.Then, considering the piecewise differentiable characteristic of time-delay, the cri-terion to output tracking performance analysis and controller design are derived by using an approach of free weighting matrix, reciprocally convex and cone complementarity linearization (CCL).Final-ly , simulation results of numerical examples show the effectiveness of the proposed approach , and il-lustrate the advantages of the proposed criteria which outperform previous criteria in the literature .
