Abstract
A concept of active structural control will be established for large optical telescopes to improve their mechanical behavior. The description of the concept starts with the mechanical design which is based on new construction principles. The mechanical performances achieved by passive means alone, will be presented first. The next step will introduce active components to perform the tight tolerances in tracking and aligning the optical components. A structured control scheme of independent loops is elaborated and discussed in some details.
