Stabilization of networked control systems with actuator saturation via delta operator approach

This paper studies the problem of estimating the domain of attraction for networked control systems via delta operator approach under a pre-designed saturated linear feedback. Ellipsoids are used as the estimates of domain of attraction for delta operator systems. A condition for the networked control system is derived in terms of an auxiliary feedback matrix for determining if a given ellipsoid is contractive invariant. Linear matrix inequalities based on the methods are developed for constructing feedback laws that achieve the stability of the systems. Numerical example is given to illustrate the effectiveness of the developed techniques.
