Passive control for networked switched systems with network-induced delays and packet dropout

Abstract

It has become a common practice to employ networks in control systems for connecting controllers and sensors/actuators on controlled plants and processes. A networked switched control system, as a special case of networked control systems, is studied. Such a system is represented with network-induced delays and packet dropout as a switched time-varying delay system. Sufficient conditions for exponential stability with strict passivity are derived for a class of switching signals with the average dwell time. Hybrid passive controller design depending on the network-induced delays and packet dropout is given in terms of linear matrix inequalities.
