摘要
区别于传统刚体控制模型, 将结构动态设计方法与控制理论相结合, 构建了光电经纬仪的柔性机电耦合控制模型, 分析了该模型的结构基频、阻尼比等机械因素与控制带宽的耦合关系, 并提出了光电经纬仪动态量化设计准则.实验表明: 光电经纬仪结构谐振频率ωn应尽可能地远大于系统谐振频率ωr, 至少满足ωn≥3ωr.该方法有效可行, 可解决高精度大型经纬仪机电谐振问题, 为设计快速响应、高跟踪精度的光电经纬仪提供了工程依据.
Abstract
Combing the structure dynamic design method with the control theory, the flexible electromechanical coupling control model was built which is difference from the traditional rigid control model. The relationship between the structural fundamental frequency and servo bandwidth was analyzed, then the dynamic quantitative design principles were put-forward, The experiment results show that, the theodolite structure frequency should be far away from the resonant frequency of the system, and meet ωn≥3ωr at least, which is effective and feasible, has solved the high precision large theodolite electromechanical resonance problem, and provide the basis of engineering for designing fast response and high tracking precision of photoelectric theodolite.
