摘要
Abstract
For the micro-vibration analysis of high resolution remote sensing satellite, a closed- loop modeling method connecting satellite structure and attitude control is presented. By building integrated simulation model based on the flexible satellite model as well as the control law and hardware properties of the attitude control system, the method can be used to predict the in-orbit response of micro-vibration signals and transfer characteristics of the satellite structure. For the example of a remote sensing satellite, the results of the time response and the structure transfer characteristics are presented and analyzed comparably, from the viewpoint of open-loop and closed loop respectively. The analysis results show that the presented method can realize the con- trol closed-loop micro-vibration analysis of the flexible satellite model, and is closer to the real case in orbit compared with the traditional open-loop simulation.关键词
