Satellite Multidisciplinary Design Optimization with a High-Fidelity Model

摘要

Satellite system design is a multidisciplinary design process that considers the space mission, payload, structure, orbit and attitude dynamics, thermal control, communication, power supply, and other parameters. Designers must balance tradeoffs among many essential systems, which can take a remarkable amount of time. Researchers have applied multidisciplinary design optimization (MDO) technology to satellite design mostly with empirical formulas [1,2]. Budianto and Olds applied the collaborative optimization (CO) method in a satellite constellation deployment problem [3]. These researches showed that MDO is effective and efficient in dealing with the coupling among multi-subsystems. The key problems to consider in engineering applications of MDO now lie in choosing the modeling technique for practical problems and implementing an optimization strategy.
