It is described general structural schemes of the composite controlled
multipanel reflecting surface of the large millimeter radio telescope’s main
reflector with frame-truss bottom, which uses hexagonal or trapezoidal mirror
shields as statically defined rigid body with controlled spatial surface.
Necessary and sufficient terms of the geometric invariability of the composite
surface are identified. Also structural properties of the multielement surface
structure and terms of its controllability are formed. The iterative
asymptotically stable in vicinity of stabilization’s surface principle of
adjusting positioning of spatial location of the reflecting surface’s fixed
points is proposed.
