机抖激光陀螺抖动控制环路频率特性的校正

Frequency-domain Performance Compensation for Dither Control Loop of Mechanically Dithered Ring Laser Gyroscope

针对所研制的机抖激光陀螺抖动控制环路带宽不够的情况,运用相位超前校正方法对环路实行校正,在保证稳定裕度和稳态精度的情况下,将环路带宽提高7倍。

To improve the bandwidth performance of dither control loop in dithered ring laser gyro, a phase leading compensation method is applied. The bandwidth is increased by seven times along with satisfactory stability and steady-state precision.
