| 摘要: |
| 针对传统的模拟抖动控制系统体积大、灵活性差的缺点，设计了一种基于单片机的新的激光陀螺数字抖动控制方法，建立了陀螺抖动的数学模型，比较研究了传统的模拟正弦波驱动和新的数字方波驱动的抖动特性，指出了后者不同于前者的抖幅变化律及非线性的随机噪声注入方式。仿真和实验证明，该方法能很好满足激光陀螺抖动控制要求，保证陀螺性能。 |

| Abstract: |
| To address the bulk and inflexibility of traditional analog dither system, a new digital dither control method for ring laser gyroscope (RLG) was designed by using single chip processor. The dither mathematical model was built and dither characteristics were investigated for square/sine wave driving signals respectively. By comparing the driving effect, it is found that the square wave driving has different variation rate of dither magnitude and nonlinear random noise infusion method. Simulations and experiments illustrate that the new method can control the RLG dither well and assure the performance. |
