液体动力陀螺仪快速启动系统研究

Research in the System for Fast Start-up of the Liquid Driven Gyro

研究了使用电磁控制方法,在火箭弹发射准备阶段,使陀螺轴快速趋近于弹轴并对其进行跟踪的控制方案。陀螺仪的信号线圈给出陀螺轴相对于弹轴的离轴角信号,经适当变换后送至电锁控制线圈,从而促使陀螺轴向降低离轴角的方向进动。文中给出了控制系统的理论模型,可为进一步的应用设计提供理论指导。仿真实验结果表明了该种控制方式的有效性。

This paper addresses an electromagnetism control scheme,which makes the inertial axis of the gyro closing to and following the axis of missile body quickly before launch of the rocket.The off-axis angle between inertial axis and body axis is picked-up by the signal coil module of the gyro.After appropriate processed,this signal is fed into the elec- tromagnetism control coil that makes the gyro to precess in the direction of reducing the off-axis angle.A mathematic model of the control system is provided here,which offers guidance for the system design in the future.Simulation shows that this method is effective.
