Abstract :
In this paper, we provide a constructive methodology for the design of decentralized control laws for a class of interconnected retarded systems subject to actuator disturbances. We consider Control Lyapunov-Krasovskii functionals for only subsystems, thus reducing the difficulty with respect to finding an overall functional, and then provide a controller which, by means of a small-gain condition, guarantees practical input-to-state stability with respect to disturbances. If the disturbances are bounded, the controller allows to drive the system variables to any small neighborhood of the origin, by suitably tuning a control parameter.
