Stability analysis and controller design for Networked Control Systems

This paper deals with typical problems of drops and large delays in networked control systems (NCSs). Considered with the existed literatures, three novel modelings are presented for drops, large delays and drops with large delays, and can include the modelings in G.R. Matias and A. Barreiro (2007) and M.B.G. Cloosterman, et al., (2007) as special cases. Then new sufficient conditions for Lyapunov stability and controller design are derived and casted as an LMI feasibility problem, according to three different modelings. Numerical examples are given to illustrate the efficiency of the proposed method.
