Delay-dependent robust stability of uncertain networked control systems with multiple state time-delays

摘要

In this paper, delay-dependent robust stability for a class of uncertain networked control systems (NCSs) with multiple state time-delays is investigated. Modeling of multi-input and multi-output (MIMO) NCSs with network-induced delays and uncertainties through new methods are proposed. Some new stability criteria in terms of LMIs are derived by using Lyapunov stability theory combined with linear matrix inequalities (LMIs) techniques. We analyze the delay-dependent asymptotic stability and obtain maximum allowable delay bound (MADB) for the NCSs with the proposed methods. Compared with the reported results, the proposed results obtain a much less conservative MADB which are more general. Numerical example and simulation is used to illustrate the effectiveness of the proposed methods.
