陀螺罗经的机动误差是罗经的一项主要指标,减少机动误差是罗经技术的一个重要方面.本文以JYJD 型陀螺罗经为分析对象,在理论分析和系统仿真的基础上,提出了一套切实可行的通过辨识舰船运动状态实现电控罗经工作状态的自动切换以减小其机动误差的方法,实践表明,该法简便易行,对减小电控罗经的机动误差效果显著. The maneuvering error of gyrocompass is one of the main indexes of compass and reducing the maneuvering error is an important aspect of compass technology.This paper takes JYJD gyrocompass as the analysis object, and based on the theoretical analysis and system simulation, presents a set of practical and feasible The method to reduce the maneuvering error of the automatic control compasses can be achieved by identifying the movement of the ship and reducing the maneuvering error. The practice shows that the method is simple and easy to implement, and has a significant effect on reducing the maneuvering error of the electric compass.
