Research on Precision Control of Large Deployable Antennas Driven by Fusion of Data and Model
摘要
Abstract
In order to improve the surface precision of large deployable planar antennas efficiently and accurately by adjusting the truss system,the surface precision prediction and accuracy verification were realized from two aspects of finite element simulation analysis and photogrammetry.According to the principle of mechanics of materials and temperature equivalence theory,the simulation model of plane antenna surface precision was constructed.A rapid measurement system of surface accuracy was established based on photogrammetry.The variable confidence Gaussian process model was estab-lished by combining the finite element simulation samples and the photogrammetry measured sam-ples,and the precision was optimized and adjusted by Bayesian optimization.The accurate prediction and on-site rapid adjustment of large planar antenna precision were realized,which may provide simu-lation analysis model support for forward precision evaluation and inverse optimization adjustment of large planar antennas.关键词
