导引头陀螺转速提取与补偿方法的研究

Research on Extraction and Compensation of Gyro Rotating Speed of Seeker

在导弹飞行试验中,对导引头陀螺转速的检测和补偿都是必要的。在无法直接获取陀螺转速的条件下,使用FFT方法分析陀螺磁钢旋转形成感应电动势的输出信号,从而提取陀螺转速和磁钢N极的相对位置,为实时检测陀螺转速并进行转速补偿提供了有效的方法。

Missile flight test requires detection and compensation for gyro rotating speed of seeker. When the rotating speed is not readily accessible,according to FFT analysis,output signal of induced electromotive force from rotation of gyro＇s magnetic steel is got so as to extract relative position between gyro rotating speed and N pole of magnetic steel,this is effective for detecting and compensating for gyro rotating speed.
