光纤陀螺稳定平台调平系统设计

Design of Platform Leveling System Based on FOG

文章简要介绍了光纤陀螺的原理及国内外发展状况;重点讨论其在平台调平系统的应用,对调平系统的组成、传递函数的阶次和系统的动态性能进行了分析和研究,提出了PI加超前校正的校正网络进行校正的方法,使系统由原来的Ⅰ型提高到Ⅱ型,消除了系统对斜坡输入的稳态误差,改善了系统的动态性能,提高了系统的调平精度。

The principle and the development situation of fiber-optics gyroscope home and abroad are introduced, and the leveling system is redesigned based on FOG. After analyzing the order and the dynamic performance of the leveling system, a correction network is designed to improve the system as a Ⅱ model one, the steady-state error caused by the ramp input is eliminated, the dynamic performance is improved and the precision of leveling is also greatly improved.
