摘　　要：灰色系统理论已成功应用于若干领域,灰色预测是灰色系统理论的重要组成部分,研究了基于灰色系统理论的航天器故障状态预测方法;首先分析了航天器故障症状变量、症状变量测量值及其变化过程的灰色表示方法,之后,研究了航天器故障状态灰色预测方法,给出并分析了利用灰色系统理论预测航天器故障状态的部分预测结果;研究表明,基于灰色系统理论的航天器故障状态预测方法是可行的。Gray system theory has been used in several fields. Gray Prediction is one of the key parts of gray system theory. Here, the method to predict fault status of satellite based on Gray System Theory is proposed. Firstly, the method using gray system theory to describe symptom variables, value of the variables, and evolution of the value of satellite fault status is analyzed. Then, the gray model for predicting fault status of satellite is studied. Finally, two kinds of results to use gray system theory to predict fault status of satellite are given, and the prediction result is analyzed. It is show that the proposed method is feasible.
