Algorithm for Controlling a Multielement Mirror using the Millimetron Space Telescope as an Example

Resumo

A new algorithm for controlling a multielement mirror of a large telescope is considered and justified in the general case for a large number of joints between rows of elements. It is intended for the creation of an effective unified control system for several objects under the constraints of budget error limits. A version of this algorithm is suggested in the autostabilization system of the Millimetron telescope. An error in the relative positioning of the elements is estimated and the sensor positions are detected. The results confirm quite successful the applicability of this control algorithm as a part of the adaptation contour of large telescopes with multielement primary mirrors.
