摘要
本文阐述了伺服系统结构设计中估算系统固有频率的必要性,介绍了一种分析和计算经纬仪方位伺服系统扭转振动固有频率的方法。
In this paper, the necessity of analysing and calculating of the inherent frequen-cy in servo-system design is described, and a method for analysis and calculating of inher-ent frequency of twisting vibration in azimuth servo system in a theodolite.
