摘　　要：无人机系统重要的侦察设备是光电载荷。为了使光电载荷获得清晰的图像,提出了新的控制策略,以抑制视轴的扰动。首先,以两轴两框架光电载荷为研究对象,分析了其结构和工作原理;然后,分析了影响视轴稳定精度的扰动因素并将其分类;接着,提出了双速度环控制策略,设计了自抗扰稳定控制器;实验研究表明,采用该视轴稳定技术的光电载荷,其扰动抑制的效果能够达到技术指标要求。The opto-electronic load is an important reconnaissance equipment of the UAV system. To obtain a clear image a new opto-electronic load control strategy is proposed for inhibiting the disturbance of visual axis. First the structure and working principle of the two-axis and two-frame opto-electronic load are introduced. Then analysis and classification are made to the disturbance factors affecting the stability of the visual axis. The dual rate-loop control strategy and an active disturbance rejection controller are applied on the opto-electronic load. The experimental results show that the opto-electronic load using the proposed lineof-sight stabilization strategy can satisfy the technical requirements of disturbance rejection.
