Abstract

The paper considers the results of the control systems development for the mm range graund based and space radio telescopes (RT), including the high precision pointing systems based on the mechanisms of parallel structure. The major problems of the RT-70 radio telescope control systems in the mm range are: designing the computer models of RT-70 dynamics and pointing drives (state identifiers) for obtaining estimates of their coordinates which are not accessible to direct measurement; designing the damping system for RT own mechanical frequencies by means of angular rate gyroscopic sensors; designing a bolometric matrix multipixel receiver which allows to reach in the contour of a control system the accuracy pointing an RT optical axis better than 3″ by controlling the separate facets of a dish adaptive surface, which is similar to optical telescopes.
