We consider a construction program control problem for orbital telescope under restrictions and parameters and structure uncertainty of its dynamic model. The calculation of needed control is based on stable to input data small errors direct technique of approximate solutions construction of route problems for controllable nonlinear systems. The modified variant of iteration algorithm calculation realization for direct technique has the structure that enables to rebuild algorithm on each calculation step by previous iteration results. Such algorithm construction enables to compute program controls for wide spectra of input data under problem statement with minimal step number. By numerical research we show that "direct" control obtained with a help stable in Tichonov sense direct technique computational algorithm for orbital telescope model as a single solid provides needed accuracy of motion realization for telescope model with non-rigid solar batteries panels and perturbed dynamical characteristics.
We represent a new approach to the development and use of a subject-oriented heterogeneous distributed computing environment for solving large-scale problems of energy security research. Both the development of scalab...
