Research on the Simulation of Small Satellite's Zero-Momentum Attitude Control System Based on STK

针对基于卫星工具包进行小卫星零动量姿态控制系统的仿真研究和应用。首先对STK的姿态属性模块和姿态仿真器的应用进行了说明;然后分析和研究小卫星零动量姿态控制系统的设计思想,同时建立小卫星的三维模型,并在STK中进行仿真应用;最后对控制规律的输出力矩数据曲线及控制精度进行分析和说明。

This paper mainly focuses on the simulation research and the application of small satellite's zero-momentum attitude control system based on STK (Satellite Tool Kit). Firstly, the STK and attitude simulator are introduced. Secondly, the design processes of small satellite's attitude control system and its three dimensional model is deeply researched and realized in the STK's scenario. Finally, the graphics of the simulation's effect is showed, the graph data of the output control torques and the precision of control logic are analyzed. This paper uses the advanced and powerful STK software in the field of satellite's system simulation and obtains perfect outcome, which will benefit the investigation of other space vehicles' system simulation and offer simulation research a novel way and means.
