舰载激光通信终端的线性自抗扰视轴稳定控制

Linear Active Disturbance Rejection Control for Shipboard Laser Communication Terminal visual axis stability

舰载激光通信终端易受到诸多复杂扰动的耦合作用,使得视轴偏离甚至产生抖动,从而影响激光通信的视轴稳定精度。针对舰载激光通信终端的扰动问题,设计了改进型线性自抗扰控制方法。仿真结果表明,与传统控制方法相比,改进型线性自抗扰控制系统具有更好的动态性能,抗干扰能力和鲁棒性更强,可以建立更加稳定的通信链路。

The shipborne laser communication terminal is susceptible to the coupling effect of many complex disturbances,which makes the visual axis deviate or even jitter,thus affecting the visual stability accuracy of laser communication. Aiming at the perturbation problems of shipborne laser communication terminal,the improved linear active disturbance rejection control method is designed. The simulation results show that,compared with conventional control methods,improved linear active disturbance rejection control system with better dynamic performance,strong anti-interference capability and robustness,and can set up a more stable communication link.
