Abstract. It is proposed the model for the active multipanel composite reflecting surface of the main reflector of the large millimeter radio telescope as large linear interval dynamic system with parametric perturbations in the absence and presence of strong interpanel ties. The problem of synthesis of optimal asymptotically stable robust regulator in the class of centralized and decentralized structures to ensure stabilization of the perturbed set of panels of the main reflector in a specified position is discussed.

Key worlds: radio telescope, composite reflecting surface, large linear system, interval models, centralized and decentralized control, robast stabilization, asymptotic stability.
