在卫星控制系统设计阶段考虑可重构性,可增强故障处理能力,对提高卫星的可靠性、可维护性及在轨生存能力具有重要意义。提出了卫星控制系统可重构性优化设计方法,该方法主要包括总体设计、子系统设计和系统分析方法。提出了功能目标设计和最小实现分析,用于建立总体设计优化方程,并考虑到子系统的性能要求;通过功能目标模型分析和反馈,可以调整设计,便于多目标设计结果的选择。最后给出了一个卫星控制系统设计的实例。
Considering reconfigurability in the early design stage of a satellite control system can improve its fault-tolerant ability, which is meaningful for increasing its reliability, maintainability and viability. An optimal design method for satellite control systems considering reconfigurability is proposed. The system design problem is primarily composed of overall design, subsystem design, and system analysis. The functionobjective design and the minimal achievement is proposed for formulating the overall design problem, considering subsystem requirements; multi-objective design can be better adjusted by the feedback form the analysis of the funetion-objective model. Finally, a simple satellite is designed to testify the design method in this paper.
