针对测试故障诊断系统可靠性的问题,在传统基于对故障航天器的参数估计模拟的故障数据仿真基础上,提出一种基于单故障叠加模型的航天器复杂故障数据仿真方法,新型数据仿真方法能够在有限次迭代的情况下逐次逼近仿真航天器故障数据,对航天器故障的仿真实验证明,该方法可广泛应用于各类航天器故障诊断系统的测试过程。

A complex spacecraft fault data simulation method based on a single fault superposition model is developed to test the reliability of spacecraft fault diagnosis systems.Unlike the traditional way of fault data simulation,which is based on simulation of parameter estimation,the new method approximates to spacecraft fault data in finite iterations.Simulation tests show the method can be extensively used in tests of different spacecraft fault diagnosis systems.
