The invention provides an embedded
large model decision control method and
system fusing multi-
modal sensing information, and relates to the field of
intelligent decision control, and the method comprises the steps: receiving multi-
modal data of a space non-cooperative target, carrying out the preprocessing and
feature extraction of the multi-
modal data, and obtaining a multi-modal sensing
information fusion model; deep semantic fusion is realized through unified
semantic space projection and a dynamic confidence weighting strategy, and a unified environment representation vector is output; constructing an input representation fusing a
time sequence context,
domain knowledge Prompt and a sample example, performing target intention recognition and
risk level evaluation in stages through a lightweight deployed
large model, and generating a structured
decision strategy; a structured
decision strategy is converted into a
spacecraft motion instruction, and a
target control sequence is solved through a designed simplified MPC controller. According to the method, the non-cooperative target sensing precision and the data utilization efficiency can be improved, the autonomous
intelligent decision-making capability of the terminal is enhanced, and safe and efficient capture and on-
orbit service tasks are supported.
