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 the reconfigurability in the design stage of satellite control system can enhance the fault handling capability and is of great significance to improve the reliability, maintainability and on-orbit survivability of satellites. A reconfigurable optimization design method for satellite control system is proposed. The method mainly includes overall design, subsystem design and system analysis. The functional goal design and minimum realization analysis are put forward to establish the overall design optimization equation and take into account the performance requirements of the subsystem. Through the analysis and feedback of functional goal model, the design can be adjusted to facilitate the selection of multi-objective design results. Finally, an example of satellite control system design is given.
