摘要: 摘要: 基于微小型两轴转台及太阳模拟器,设计了一种太阳敏感器光学信号动态激励系统,适用于卫星控制分系统闭路验证过程.通过对光源、光路、积分器、准直镜的合理选型、设计,使得模拟光的辐照度、准直度、辐照不均匀度、辐照不稳定度达到了控制分系统闭路验证的性能要求.通过结构设计、滑环设计、伺服控制设计,实现了0.02°的转台角度控制精度,以及360°全范围的角度空间可达.综合试验结果表明,该激励系统能够实现卫星在全天球范围内运行过程中对太阳敏感器的有效信号激励,能够应用于控制分系统的闭路验证系统.

Abstract: Abstract: Based on micro twoaxis turntable and sunlight simulator, an optical signal dynamic excitation system of sun sensor is designed, which is suitable for closedcircuit verification of satellite control subsystem. Through the reasonable selection and design of light source, optical path, integrator and collimator, the irradiance, collimation, irradiance nonuniformity and irradiance instability of the simulated light meet the performance requirements of closedcircuit verification of the control system. Through the designs of structure, slip ring and servo control, the turntable angle control accuracy of 0.02°and 360°angle space can be achieved. The comprehensive test results show that the excitation system can excite the sun sensor effectively during the satellite’s maneuvering in the whole sky, and can be applied to the closedcircuit verification system of the control system.

Key words: Keywords: sun sensor, closed loop verification, dynamic excitation, control system
