Autonomous spacecraft unexecuted planning sequence resource anomaly detection and repair method

Abstract

The invention relates to an autonomous spacecraft unexecuted planning sequence resource anomaly detection and repair method, and belongs to the technical field of spacecraft autonomous task planning repair. In an execution stage of a spacecraft task planning sequence, for a given spacecraft non-execution planning sequence, the total consumption of different resources by actions in the sequence isroughly estimated, the time when the different resources are abnormal for the first time is determined and recorded, and the end point moment of resource restoration is determined. And for different abnormal resources, searching and a resource restoration action sequence is determined by adopting a task planning restoration method based on state back-off before an abnormality occurs for the firsttime, recording all feasible restoration schemes, and selecting a scheme with the minimum resource consumption sum from the schemes. And finally, in order to integrate with an original non-executed planning sequence, a resource supply action and a regression action sequence are added after the scheme, and properly adjusting the start time of the action, so as to obtain a final feasible task planning sequence without resource abnormality.

Description

technical field [0001] The invention relates to a method for detecting and repairing resource anomalies in an unexecuted planning sequence of an autonomous spacecraft, in particular to an autonomous anomaly detecting and repairing method for replenishing consumable resources in an unexecuted planning sequence of a spacecraft during the task execution process, and belongs to spacecraft Autonomous Mission Planning Restoration Technical Field. Background technique [0002] With the continuous progress and development of artificial intelligence technology, the autonomy of spacecraft has gradually become one of the hot research directions in the aerospace field. For near-Earth satellites, the uploading of mission operation instructions is limited to the measurement and control arc of the ground station, which restricts the timely discovery and quick resolution of faults in the execution of the ground; Due to the huge time delay, relying only on the ground to provide the sequence...
