激光陀螺抖动控制电路高精度数字化设计

随着激光陀螺电路系统数字化,小型化的不断发展。传统的机抖激光陀螺模拟偏频系统由于存在体积大,难以进行精确控制的缺点而在使用中受到极大限制。本文设计了一种基于DSP的数字机抖偏频控制系统,提出了数字机抖偏频控制系统原理,实现了一种周期性锯齿波噪声的注入。实验结果表明,数字机抖控制系统工作稳定,激光陀螺测量精度高。

Design of the digital dither control circuit on laser gyro

As the laser gyro circuit system development of Digital and miniaturization. Traditional laser gyro circuit system is large and difficult to accurately control the faults and restricted in use. This paper designs a digital dither control circuit based on dsp, put forward the digital dither control circuit theory, and to achieve a periodic sawtooth noise injection. The experimental results shows that, the digital dither control circuit stability, the laser gyro had a higher measuring accuracy.
