Abstract
AbstractTo increase the degree of validity of design decisions when creating a small spacecraft, a methodological approach is proposed for the structural–functional synthesis of the appearance of its onboard systems. The proposed approach allows to perform multi-criteria selection of effective configuration variants for onboard system of a small spacecraft, taking into account various types of structural reservation of onboard equipment, a wide assortment of element base. The conceptual and mathematical formulations of the problem of structural and functional synthesis of the appearance of the onboard system of a small spacecraft are presented. An algorithm has been developed for multi-criteria synthesis of the appearance of the onboard system of a small spacecraft, which is based on the interval lexicographic method for removing criterial uncertainty. An illustrative example of finding a given number of rational variants for implementing a motion control system for a small spacecraft uniformly located in the Pareto region is given. This technique allows even at the stage of the spacecraft designing to reduce significantly the number of design errors by the decision-maker, as well as to improve the quality and efficiency of the application of the created space systems.
