| 摘 要： | 针对动中通系统的稳定跟踪问题,采用一种以期望工作状态为假设对象的逆向分析方法,对一类典型的三轴动中通系统进行了稳定机理分析。在分析三轴稳定机理的基础上,选取2种姿态传感器安装方式,设计了2种与之对应的前馈稳定和闭环稳定三轴自稳定结构,并成功应用于实际系统。通过实验分析比较了2种三轴自稳定结构的特点和性能。实验结果表明,与前馈稳定结构相比,闭环稳定结构鲁棒性更好,稳定精度更高,且易于同其他高级控制算法相结合提高系统稳定精度,更符合动中通系统在复杂多变的环境中高精度稳定跟踪的工程应用要求。

| Abstract: | In view of the stable tracking problem of a mobile satellite communication system,a reverse analysis method based on the desired working status assumption is used to analyze the tri-axial stabilization mechanism of the mobile satellite communication system.Two installation methods of the gyros are chosen according to the analysis,and two corresponding self-stabilized structures,the feed forward stable structure and the closed-loop stable structure,are designed and applied to the real system successfully.The... |
