Sampled-data control for a class of two-stage dissolution tank systems

This paper deals with the network control of two-stage dissolution tank systems. A class of sampled-data control of time delay systems with actuator saturations is modeled. We transformed non-linearities of actuator saturations in the systems into a convex polytope of linear system, and the sampled-data control problems are solved by input delay approach. Then, using the Lyapunov-Krasovskii stability method, delay-dependent sufficient conditions for asymptotic stablizability of the systems were proposed, and an estimate of the domain of attraction is presented correspondingly. Finally,numerical simulations are given to demonstrate the validity of the results.
