摘要

In this paper, the problems of networked control for delta operator systems with actuator saturation are considered. Ellipsoids are used to estimate the domain of attraction for the networked control systems with actuator saturation. 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. Discussions on the networked control systems performance optimization on expansion of the domain of attraction are presented. A numerical example on one-link PMW-controlled joint driven by pneumatic muscles is given to illustrate the effectiveness of the developed techniques.
