Embodiment approach

[0029] Such as figure 1 As shown, according to an embodiment of the present invention, the spacecraft autonomous health management method based on feedback control of the present invention includes:

[0030] S1. Make a failure plan for each functional system on the spacecraft, and input the failure plan into the central control system of the spacecraft;

[0031] S2. The central control system acquires the telemetry data used in the fault plan through the telemetry acquisition channel, wherein the telemetry data includes the first telemetry data and the second telemetry data;

[0032] S3. The central control system selects the first telemetry data and the second telemetry data used in the failure plan from the collected telemetry data, and compares the selected telemetry data with the corresponding preset threshold in a fixed period, if If the preset threshold is exceeded, the central control system sends a fault handling instruction for processing the fault according to the f...

Abstract

The invention relates to an autonomous health management method for a spacecraft based on feedback control, comprising the following steps of: S1, establishing a fault plan for each functional systemon the spacecraft, and inputting the fault plans to the central control system of the spacecraft; S2, acquiring the telemetry data used by the fault plan by the central control system through a telemetry acquisition channel, wherein the telemetry data comprises first telemetry data and second telemetry data; and S3, picking up the first telemetry data and the second telemetric data used by the fault plan from the acquired telemetry data by the central control system, comparing the picked telemetry data with the corresponding preset threshold in a fixed period, and sending a fault handling instruction for processing the fault according to the fault plan by the central control system if the preset threshold is exceeded. By means of the interconnection relationship between the telemetry dataand the fault handling instruction, the program control capacity of the spacecraft is played, so that the autonomous handling for the on-orbit faults of the spacecraft is achieved.

Description

technical field [0001] The invention relates to a method for autonomous health management of a spacecraft, in particular to a method for autonomous health management of a spacecraft based on feedback control. Background technique [0002] During the flight mission of traditional spacecraft, the ground flight controller mainly relies on the downlink telemetry data to monitor the status of the spacecraft, and when problems are found, send uplink commands or inject data for troubleshooting. All of these require a longer period of measurement and control coverage area, experienced flight control staff and a complete on-orbit failure plan. For spacecraft that need to operate in orbit for a long time, such as space stations and extraterrestrial resident bases, it is not realistic to rely on ground personnel to monitor the status with high intensity for a long time. Stable operation. [0003] The on-orbit working conditions of the spacecraft are mainly judged by the telemetry dat...
