This paper presents a kind of controller design method for a class of networked control systems（NCSs）with multiple packet dropouts,where the number of consecutive packet dropouts is limited by a known upper bound.A novel model that can be used to describe multiple packet dropouts in both sensor-to-controller and controller-to-actuator sides is provided.A sufficient condition for mean-square asymptotic stability is derived for the closed-loop networked control system,which is dependent on the upper bound of the packet dropouts *** corresponding state feedback control law is presented in terms of linear matrix inequalities（LMIs）.A networked control system for an inverted pendulum is finally provided to show the effectiveness and applicability of the proposed method.

This paper investigates the problem of robust H-infinity state estimation for a class of uncertain discretetime piecewise affine systems where state space instead of measurable output space partitions are assumed so that the filter implementation may not be synchronized with plant state trajectory transitions. Based on a piecewise quadratic Lyapunov function combined with S-procedure and some matrix inequality convexifying techniques, two different approaches are developed to the robust filtering design for the underlying piecewise affine systems. It is shown that the filter gains can be obtained by solving a set of linear matrix inequalities （LMIs）. Finally, a simulation example is provided to illustrate the effectiveness of the proposed approaches.

This paper investigates the problem of robust exponential H∞ static output feedback controller design for a class of discrete-time switched linear systems with polytopic-type time-varying parametric uncertainties. The objective is to design a switched static output feedback controller guaranteeing the exponential stability of the resulting closed-loop system with a minimized exponential H∞ performance under average dwell-time switching scheme. Based on a parameter-dependent discontinuous switched Lyapunov function combined with Finsler＇s lemma and Dualization lemma, some novel conditions for exponential H∞ performance analysis are first proposed and in turn the static output feedback controller designs are developed. It is shown that the controller gains can be obtained by solving a set of linear matrix inequalities （LMIs）, which are numerically efficient with commercially available software. Finally, a simulation example is provided to illustrate the effectiveness of the proposed approaches.
