NASA已与通用功力公司签订了设计和研究先进的半人马座(液体推进的上面级)的合同,以支援1985～1986年进行的Galileo 和Solar Palar 星际飞行任务。航天飞机机载半人马座的控制系统必须满足空间运输系统的安全要求,即在整个飞行任务中执行关键性功能时,必须进行双容错控制。在多个部件发生故障,以及在系统的诸计算机中存在严重的时间-相位不同步的情况下,该控制系统的完善性是通过实时计算机仿真进行检验的。这种仿真模拟了控制硬件,分系统接口,嵌入式的软件处理,逐根导线,以便引入故障。直观功能是通过图形和诊断软件达到的。通过Monte Carlo 仿真分析,验证了半人马座的控制系统。
NASA has signed a contract with General Utilities to design and research the advanced Centaur (liquid-propelled upper level) contract to support Galileo and Solar Palar interplanetary missions from 1985 to 1986. Space Shuttle Centauri control systems must meet the space transportation system’s safety requirements that double fault-tolerant control is required when performing mission-critical functions throughout the mission. The integrity of the control system was verified by real-time computer simulation in the event of multiple component failures and serious time-phase out-of-phase conditions in the computers of the system. This simulation simulates the control hardware, subsystem interfaces, embedded software processing, by the wire, in order to introduce fault. Intuitive features are achieved through graphics and diagnostic software. Through Monte Carlo simulation analysis, verify the centaur’s control system.
