Stabilization of networked control systems in the presence of packet losses

摘要

The problem of stabilization of networked control systems (NCSs) in the presence of packet losses is studied. Sufficient conditions on the stability and stabilization of the NCSs are presented. Stabilizing state feedback controllers can be constructed by using the feasible solution of some linear matrix inequalities (LMIs). The novelty of this work is that the NCSs with arbitrary but finite data packet dropout are modelled as switched linear systems, and this enables us to apply the existing theories of switched systems to the analysis of such NCSs. A simulation example is worked out to illustrate the effectiveness of the proposed method.
