摘要：在空间激光通信瞄准、捕获、跟踪系统中，其中一个关键难点问题是在较大的瞄准范围内实现高精度的静态指向和快速的动态响应。为了提高跟瞄精度和跟瞄带宽，本文采用一种新型高精度指向机构，提出位置环和电流环的双闭环控制器，并设计陷波滤波器来抑制系统谐振。最后，基于Matlab/Simulink搭建精瞄指向机构控制系统的仿真平台，以验证算法的控制性能。仿真实验结果显示：设计的控制策略在输入角度幅值为±001°时，系统带宽可达22461 Hz；在角度幅值为±2°，带宽可达305176 Hz；同时静态指向精度均可控制在±15 μrad范围内。

Abstract: Application of Maglev technology for the flywheel rotor controlling has many advantages, but the stability of the flywheel rotor that under the high speed has become a key problem. Based on the analysis of the composition and the working principle of magnetic levitating bearing rotor system, compared several kinds of filter and verified the related experimental results. Studies have shown that Chebyshev filter can stabilize the rotor rotation to the regulation speed effectively, and complete the provisions of the charge and discharge test.
Key words: flywheel rotor; Chebyshev filter; magnetic levitation control
