The invention discloses a health early warning method for an attitude and orbit control subsystem, and the method comprises the following steps: S1, dividing the attitude and orbit control subsystem into a plurality of feature blocks, and setting the health weight coefficient of each feature block; s2, performing health state real-time evaluation on each feature block to obtain a real-time health state score and a health influence coefficient of each feature block; s3, calculating the real-time health state of the attitude and orbit control subsystem by combining the health weight coefficient, the health state score and the health influence coefficient of each feature block; and S4, estimating the future health state of the system according to the real-time health state value of the attitude and orbit control subsystem, and performing health early warning when the estimated value exceeds an alarm value. According to the invention, early warning can be carried out on the health state of the attitude and orbit control subsystem, and in-orbit autonomous health management of the attitude and orbit control subsystem is realized.

    本发明公开了一种姿轨控分系统健康预警方法,包含以下步骤:S1、将姿轨控分系统划分为若干特征块,并设定各特征块的健康权重系数;S2、对各特征块进行健康状态实时评估,得到各特征块的实时健康状态分值及健康影响系数;S3、结合各特征块的健康权重系数、健康状态分值及健康影响系数,计算姿轨控分系统的实时健康状态;S4、根据姿轨控分系统的实时健康状态值预估系统的未来健康状态,当预估值超过警戒值时,进行健康预警。本发明可对姿轨控分系统的健康状态进行预警,实现姿轨控分系统的在轨自主健康管理。
