A high-precision formation control method based on accelerometer combination adopts an accelerometer to be accessed into a control loop to measure the star acceleration in real time, accelerometer drift compensation parameters are estimated, a thruster calibration coefficient is dynamically acquired in a control process, dynamic feedback and correction of formation control quantity are achieved, the method is not limited by configuration conditions of an executing mechanism and can be autonomously achieved on a satellite, the problem that in the prior art, formation satellite high-precision control under the working conditions of different configuration scales and control tasks is difficult to achieve is solved, and the method is more suitable for engineering practice and wider in application range.

    一种基于加速度计组合的高精度编队控制方法,采用加速度计接入控制回路实时测量星体加速度,通过预估加速度计漂移补偿参数,控制过程动态获取推力器标定系数,实现编队控制量动态反馈与修正,不受执行机构配置条件限制,同时能够在星上自主实现,解决了现有技术中难以实现在不同构形尺度及控制任务工况条件下的编队卫星高精度控制问题,更贴合工程实际,适用范围更广。
