激光接收器的抖动抑制优化控制方法

Optimal control method for jitter suppression of laser receiver

为了提高激光接收器的精度,解决传统方法存在缺陷,提出激光接收器的抖动抑制优化控制方法。首先采用闭环抖动控制方案对激光接收器的机抖频率和幅度实施控制,通过抖动幅度闭环控制器采用自动幅度控制环路控制抖动,依据抖动的正弦波幅度调整形式注入随机抖动,然后融入抖动随机噪声,过滤掉激光接收器的动态锁区,提出了噪声注入的优化方法,给出优化后噪声注入压缩动态锁区方案,解除激光接收器动态锁区,最后对激光接收器的抖动进行有效抑制。实验结果表明,该方法的激光接收器具有较高抖动抑制能力。

In order to improve the accuracy of laser receiver, to solve defect of traditional mechanical vibration control method, optimization control method for suppressing forward laser receiver jitter is proposed. Firstly, using the closed-loop to adaptive control the laser receiver dither frequency and amplitude. Then the random jitter is injected in- to the system according to the sine wave amplitude adjustment. And secondly the random noise is fused to filter the dy- namic locking region of the laser receiver. The optimization method of noise injection is put forward to give the opti- mized dynamic compression region scheme, which can relieve the jitter of the laser receiver. The experimental results show that the proposed laser receiver has a stronger ability.
