摘要

为了实现快速反射镜系统(FSM)的性能预测和快速设计，建立了两轴FSM的动力学模型，并提出了基于该动力学模型的FSM设计方法。介绍了FSM的结构与工作原理，推导了FSM的理想动力学模型，分析了FSM的高阶谐振和轴间耦合，建立了二自由度FSM整体模型。基于该模型，设计了某型FSM的主要参数，并进行了性能仿真。根据所设计的参数制作了FSM试验样机，测试了样机性能。试验结果表明：模型性能仿真结果与试验样机测试结果基本一致，系统带宽达到250 Hz以上，调节时间小于15 ms，超调量小于8%，定位精度优于20 rad。结果表明，设计的FSM样机性能满足指标要求，验证了该设计方法的有效性和正确性。

Abstract

To design a Fast Steering Mirror (FSM) system rapidly and to predict its performance

a FSM dynamic model with two Degree of Freedom (DOF) was established

and a design method for the dynamic model-based design of FSM was investigated. The structure and operating principle of the FSM was described

and an ideal dynamic model of FSM was derived. Then

the high-order resonance and the coupling between the axes were analyzed and a two DOF integrated model of FSM is established. Based on the FSM model

main parameters for the FSM were determined. According to the design parameters

a FSM prototype was produced and its performance was tested. The results indicate that the simulation performance obtained by the FSM model is coincident with the experimental performance of the FSM prototype well. Moreover

the FSM shows its bandwidth more than 250 Hz

adjusting time less than 15 ms

overshoot less than 8%

and position accuracy better than 20 rad. These results demonstrate that the FSM prototype can satisfy the design requirements. It verifies the validity and correctness of the design method.
