飞行控制软件可靠性设计

The Reliability Design in Flight Control Software

针对双ＣＰＵ、以主从方式运行的冗余硬件配置，介绍了管理和故障诊断策略。飞行控制软件一般包括制导、姿控和综合三部分，制导部分要求有高的计算精度，姿控部分的实时性很强，综合部分应对飞行状态正确识别和处理。针对这些特点，分别介绍了各分系统软件可靠性设计的总体结构、故障判别的条件以及具体的实现。文中提到的部分技术经过了实验的检验。

The reliability design technology in the field of flight control software for launch vehicles is introduced. In view of dual CPU and redundant hardware configuration which works in primary and secondary forms, the management and failure diagnosis for this system are described first. Then, the reliability design in guidance, attitude control and comprehension software, which are the three major parts of flight control software is proposed. The technology introduced above is verified to be feasible and fault tolerant by experiments.
