Structural Optimization of Satellite Based on MultiObjective Collaborative Optimization Algorithm

Abstract

Abstract:

Abstract： Aimed at the time-consuming problem of multiobjective and multiconstrained structure optimization of satellite system, a multiobjective collaborative optimization model was proposed for satellite structure. A COPE(collaboartive optimization and parto explorer) combinatorial optimization method was presented by combining collaborative optimization with the global multiobjective optimization algorithm, and taking some improvement measures in view of the defects of collaborative optimization. The multiobjective optimization of a satellite was taken as an example, where iSIGHT was used to conduct the multiobjective optimization of satellite structure. Then, the Pareto optimal set was obtained by adopting COPE. The results show that the multiobjective collaborative optimization model can simplify the complexity of optimization problem, and the COPE combinatorial optimization method based on the approximation model has good accuracy and efficiency. This method provides a certain reference value for similar complex structure optimization problem.

Key words: structural optimization of satellite, collaborative optimization, global multiobjective optimization
