大型网状可展开天线的动力学与控制研究进展

内容简介：随着卫星移动通信技术的迅猛发展，为了提高卫星天线增益，普遍采用大型网状可展开抛物面天线。由于该类天线具有质量惯量大、展开过程耗时长、低刚度等特点，其展开过程和在轨正常工作期间，对卫星的动力学和姿态控制有较大影响。文章首先对大型网状可展开天线的特点及其对卫星动力学与控制的影响进行介绍，然后对大型网状可展开天线带来的动力学与控制相关问题进展进行了综述，包括：大型网状可展开天线展开状态动力学建模、展开状态试验验证、展开过程动力学建模、展开过程姿态控制及在轨天线指向控制等。最后对采用大型网状可展开天线的动力学与控制研究方向进一步需深入开展的工作提出了建议。

Abstract：With the development of mobile communication technology ,the large deployable parabolic mesh reflectors are wildly used to improve the antenna gain . Considering the large inertia , long-period deployment , and low stiffness properties , these antennae have a great influence on the dynamics and control of the satellites . Firstly , the structural characteristics and its influences on the dynamic and control of the whole-satellite were introduced for the large mesh deployable antenna . Secondly , the dynamic and control problems were discussed , such as dynamic modeling of the deployed antenna , verification method of the deployed dynamic model , multi-body dynamics of the deploying antenna , deploying-process attitude control , and pointing control of the antenna , and so on . Finally , the prospects of the dynamics and control of the satellite with large deployable antenna were presented .
