Large-Scale Multidisciplinary Optimization of a Small Satellite’s Design and Operation

摘要: The design of satellites and their operation is a complex task that involves large number variables multiple engineering disciplines. Thus, it could benefit from the application multidisciplinary optimization, but previous efforts have been hindered by complexity modeling implementation, discontinuities in space, wide range time scales. We address these issues applying new mathematical framework for gradient-based optimization automatically computes coupled derivatives system via generalized form adjoint method. modeled disciplines are orbit dynamics, attitude cell illumination, temperature, solar power, energy storage, communication. Many include functions with nonsmooth regions addressed to enable numerically exact computation all variables. wide-ranging scales ...
