| 摘 要： | 复合轴是双通道控制的一种实现结构，可大幅度提高光电跟踪系统的跟踪精度和响应频率，在光电跟踪观测、激光通讯和光束稳定控制中有着广泛应用。在高精度跟踪控制领域，复合轴控制技术是实现微弧度角秒级甚至亚微弧度非常有效的手段。文中介绍了复合轴跟踪系统的基本原理和主要技术问题。在复合轴控制系统中，主轴、子轴的控制带宽匹配是实现复合轴控制技术的前提，子轴（快速反射镜）的精度是复合轴精度的制约。重点分析了复合轴跟踪系统近年的发展与技术进步，如多重复合轴、虚拟复合轴以及自适应光学和复合控制等技术在复合轴系统中的应用等。 |

| Abstract: | Compound axis servomechanism is an engineering realization of the two-channel control system, and is widely used in the optoelectronic tracking control, laser communication and beam control. The tracking precision and control bandwidth are greatly improved by the compound axis servomechanism. In high tracking control system, the compound axis servomechanism is an effective way to obtain the tracking precision of the microradian, even the submicroradian. In this paper, the basic theory and primarily technical problems of the compound axis servomechanism were introduced. In the control system of the compound axis servomechanism, the control bandwidth matching of main and subsystem tracking control was a prerequisite of compound axis servomechanism, and the control performance precision of compound axis servomechanism depended on the closed loop control performance of fast steering mirror. The recent development and technical improvement was analyzed, such as multiple compound axis servomechanism, pseud compound axis servomechanism, adaptive optics, feed forward control and so on in the compound axis servomechanism. |
