Abstract

For the large space structure assembled in orbit of individual building elements, the angular motion equations were derived. Consideration was given to the discrete nature of variations of the mechanical structure and substantial structural elasticity induced by the flexible joint couplings of the framework elements. A procedure was proposed for computeraided analysis of the variations of the dynamic characteristics of the assembled structure as the control plant whose model has variable coefficients and strongly pronounced characteristics of the elastic multifrequency oscillatory system. For such objects, a sequence of variable motion control strategies was formed to provide highly-precise control which is stable to the elastic oscillations at all stages of assembling. For the developing structure, the structural diagrams of the orientation systems realizing the accepted control strategies at the corresponding stages of assembling were presented. The results of modeling corroborating operability of the proposed control algorithms were analyzed.
