STABILIZATIO N OF DISCRETE-TIM E INTERCONNECTE D SYSTEMS USING A RECEDIN G HORIZO N CONTRO L *

We consider the problem of stabilizing a discrete-time large scale uncertain system consisting of interconnected subsystems via decentralized controllers. The norms of the controls are a priori bounded and the uncertainties are supposed to be cone-bounded. In a neighbourhood of the origin system can be stabilized by decentralized non­ linear feedbacks. We use a receding horizon type control, if the initial state of the system is outside of this set.
