摘要
研究一种基于G2的集故障注入、故障模拟和故障诊断为一体的半物理仿真系统,包括基于VxW orks的实时硬件模拟系统、星载姿轨控计算机、数管及遥控遥测模拟器和专用接口箱等.开发了基于G2的以某一类典型卫星控制系统为对象的故障诊断专家系统,并对G2外部接口进行了扩展设计.最后,以典型故障为例,在半物理仿真平台上进行了演示验证.
A hardware-in-loop simulation platform based on G2 is introduced.This platform is made up of real-time hardware simulation system based on VxWorks,onboard attitude and orbit control computer,onboard data handling simulator,command and telemetry simulator,and special interface testing system etc.The functions include fault injection,fault simulation and fault diagnosis.A fault diagnosis expert system of one kind of typical G2 based satellite attitude control fault diagnosis is designed.And at the same time,the G2 interface is developed.Lastly,taking a typical satellite attitude control system for example,a demonstration experiment is carried out on the simulation platform.
