Abstract

The invention relates to a heterogeneous gyroscope fault positioning and processing method based on multi-source information, and belongs to the field of spacecraft control. The method comprises the following steps: (1) judgment of a gyroscope single-machine hardware measurement fault; (2) gyroscope power-up fault and autonomous closing treatment; (3) gyroscope single-machine software-level data information judgment and system-level equivalent detection; and (4) gyroscope fault switching treatment. According to the gyroscope assembly reconstruction combination processing method, the discrimination logic is perfected according to the principle of consistency and completeness, and the redundant combination use efficiency of gyroscopes of different types, configurations and numbers is improved.

Description

technical field [0001] The invention relates to a heterogeneous gyroscope fault location and processing method based on multi-source information, belonging to the field of spacecraft control. Background technique [0002] A satellite is equipped with a set of 4S hemispherical resonant gyroscope and a set of 3+1S double-floating gyroscope. The two-floating gyroscope and the hemispherical resonant gyroscope are used as the inertial attitude sensor of the control system. The gyro used can be switched. [0003] For the heterogeneous configuration of two sets of gyroscopes, the existing technology at home and abroad usually only selects the measurement of one set of gyroscopes at the same time to introduce a closed loop to participate in the three-axis attitude control, and in the fault diagnosis process of each set of gyroscopes, the status information of the stand-alone hardware level , stand-alone software-level data information, and important parameter status are processed s...
