Abstract
To create an effective unified control system for several objects in the conditions of error budget constraints, a new algorithm for controlling a multi-element mirror of a large telescope is generally considered and justified in the general case for a large number of joints between element rows. A version of this algorithm is suggested in the autostabilization system of Millimetron. An error in the relative positioning of the elements and the search for the location of the sensors was evaluated. The results obtained make it possible to state quite accurately the successful applicability of this control algorithm as a part of the contour of adaptation of large telescopes with multi-element primary mirrors.
