某型电控罗经作为当前主要的一种提供真北基准的指向仪器,建立其多误差条件下的主轴运动模型及其仿真平台,对其进一步研究具有重要的实际意义。本文根据其工作原理,首先针对性分析速度误差、纬度误差和惯性误差的影响,建立了电控罗经陀螺仪主轴直航向等速运动数学模型;进而利用SIMULINK工具建立其仿真模型,并通过比较仿真数据与实装观测结果,验证了模型建立的合理性和准确性。

Electromagnet control gyrocompass is a main instrument providing a true north heading .The research on establishing the gyro axis motion model and simulation platform of electromagnet control gyrocompass with much error conditions has an important practical significance. According to its working principle, the mathematical model of the direct heading with constant velocity motion of the gyrocompass is established by analyzing the influence of velocity error, latitude error and inertial error. Then the simulation model is established with toolbox SIMULINK toolbox.The rationality and accuracy of the model are verified through comparison of simulation data and actual observation results.
