| 摘 要： | 结合卫星加速度模式无拖曳控制系统一般组成、各环节典型模型、常见控制器及天琴一号空间惯性基准建立试验卫星的采样周期与控制周期,着眼于工程实际问题的挖掘与解决,重点阐述了该卫星CIC滤波器组频响特性等效、加速度模式无拖曳控制系统稳定裕度及残余加速度指标分析与综合等技术内容。研究表明,多周期离散系统真实稳定裕度难于准确预测;积分系数是决定PSD指标的关键参数;抗混淆滤波器是提升时域残余加速度指标的关键环节,且有利于抑制高频数据在PSD低中频段的高频折叠;在未引入抗混淆滤波器的情形下,频域指标统计应以进入控制器的残余加速度数据为准。在轨飞行试验结果与仿真结果基本吻合。

| Abstract: | The typical drag free control system structure, the representative model of each link, and the common controller as well as the sampling period and controlling period of TQ 1 space inertial reference test satellite are introduced in this paper. Focusing on the excavation and solution of the practical engineering problems, the CIC filters bank frequency response and its equivalence, and the stability margin analysis of an acceleration mode drag free control system and its residual acceleration synthesizing are emphasized. It shows that the true stability margin of the system can’t be predicted accurately, the integral coefficient is crucial to the PSD index of the residual acceleration, the anti alias filter is the crucial link to raise the time domain index and beneficial to restrain frequency folding of the high frequency data to the low and middle frequency band, and the residual acceleration data entering into the controller should prevail in the index statistics in frequency domain. The in orbit test results are in good agreement with the simulation results. |
