| 摘 要： | 二频机抖陀螺具有较高的精度,但在每个抖动周期需要两次通过锁区,会丢失部分信息,从而带来了过锁误差.噪声注入只能将误差随机化,并不能从根本上消除误差.根据锁区方程阐述了锁区对机抖陀螺精度的影响.对二频机抖陀螺的锁区补偿方案进行了理论研究.采用零速率点恒加速近似得到了过锁误差的信号表征方法.数值分析表明该锁区补偿方法在各种...

| Abstract: | The mechanical dither ring laser gyro(MDRLG) can achieve high accuracy.But the MDRLG must go across lock-in region twice every dither cycle,thus the information loss is inevitable.Random noise injection in the dither amplitude can only cancel the accumulation of lock-in error,but not the error itself.According to the lock-in equation,the side effect of lock-in phenomenon is interpreted in detail.Theoretical research on lock-in error compensation for MDRLG is carried out.Taking the constant acceleration appr... |
