Effect of Platform Servo System with Pulse Modulation on Gyroscope Drift

介绍了在平台式惯导系统中 ,由脉冲调宽加矩方式控制的惯性稳定平台的角振动对陀螺漂移所产生的影响。从理论上分析了在线振动条件下影响陀螺漂移的因素。通过对平台稳定系统的动态仿真 ,得出了陀螺漂移与采用脉宽调制工作的稳定回路参数之间的关系 ,为惯性平台稳定回路的设计提供重要的数据依据。

In this paper,the effect of the angle vibration of platform is introduced,in which the pulse modullation of servo loops is made to reduce the gyroscope drift in the INS.Main factors that influence gyroscope drift under the linear vibrating condition are theoretically analyzed.By means of the dynamic simulation of the platform servo system,the relation between the gyroscope drift and the parameter of servo loop is determined.It provides important data for the future design of the platform servo loop.
