基于并联平台的卫星微振动控制研究进展

高分辨率已经成为了目前我国卫星发展的一个重要方向,在这进程中必须要攻克的一个重要技术难题就是对卫星微振动的控制.首先综述了国内外在使用并联平台解决微振动控制问题方面的发展情况,主要是平台研制及性能情况对比,对比发现,基于并联平台的微振动控制技术我国目前相比于国外还存在一定差距.然后对并联平台的典型构型设计、动力学建模、控制系统设计、平台优化以及地面模拟试验等研究进行了详细的总结.最后对我国微振动控制技术未来需要进一步深入研究的问题提出了展望.

RECENT PROGRESS OF SATELLITE MICRO-VIBRATION CONTROL BASED ON THE PARALLEL PLATFORM

The high-resolution capability is an important development direction for satellite in our country. In this respect, a key technique is the satellite micro-vibration control. This paper reviews the developments of the parallel platform for solving the problem of micro-vibration control in China and abroad, with a comparison of the platform manufacture and the performance conditions. It is shown that the level of the micro-vibration control technology based on the parallel platform in China is still some way behind those of other advanced countries. This paper reviews the typical configuration design, the dynamics modeling, the control system design, the platform optimization and the ground test of the parallel platform. The further research directions for the micro-vibration control technology in our country are suggested.
