Switching controllers for networked control systems with packet dropouts and delays in the sensor channel

In this paper, discrete-time networked control systems (NCS) with packet dropouts and bounded-and-known delays in the sensor channel in a worst case setting are considered. Such systems are modeled as time-varying switching systems and analyzed by means of recent results in the area of switching control. By means of these results it is shown that: (a) such systems can be stabilized by a switching observer based controller if and only if a set of linear matrix inequalities (LMIs) are satisfied and (b) the satisfaction of such conditions allows to parameterize any family of stabilizing switching controllers.
