摘要:

卫星的能源分系统设计和验证是卫星设计的关键环节。能源分系统具有高安全和高可靠的要求,其设计过程与卫星轨道、光照、工作模式等多重因素耦合,同时需要与机械、热、供电、控制等多学科关联设计。为快速、便捷、全面实现复杂系统的设计和仿真,提出基于模型的系统工程(model-based system engineering, MBSE)方法,通过模型实现能源分系统多耦合、多产品、高安全系统的显式一体化表达,围绕需求展开多个功能点和性能点的设计、验证与优化。结果表明,所提方法构建的设计验证一体能源设计模型可对系统需求做精细化分析,进而进行功能和结构设计,实现和优化系统性能指标设计,并完成对需求的闭环和验证,在工程中具有高效、明确的应用价值。

Abstract:

The design and validation of satellite power subsystem is a key part of satellite design. The power subsystem has high safety and high reliability requirements, and its design is coupled with multiple factors such as satellite orbit, lighting, and work mode. Meanwhile, it needs to be associated with multi-disciplinary design such as mechanism, thermology, power supply and control. In order to realize the design and simulation of complex system quickly, conveniently and comprehensively, the model-based system engineering (MBSE) method is proposed to realize the explicit integrated expression of multi-coupling, multi-product and high-safety system of power subsystem through the model. In addition, the design, verification and optimization of multiple function points and performance points are carried out around the requirements. The results show that the power design model constructed by this method integrates design and verification, it can make a refined analysis of the system requirements, and then carry out functional and structural design, realize and optimize design of system performance indicators, and complete the closed-loop and verification of requirements, which has efficient and clear application value in engineering.

Key words: model-based system engineering (MBSE), satellite, power system, requirement analysis, architecture design
