捷联稳定技术在两轴光电跟踪仪中的应用

摘要

The photoelectric tracker is interfered by carrier's swaying which is the key factor of preventing the stabilization and the tracking precision from being improved. Firstly, based on control theory, this article compared direct-stabilization with indirect-stabilization. Secondly, the mathematic model of indirect-stabilization on two-axis optoelectronic tracking platform is established. Finally, a two-axis optoelectronic tracker used indirect-stabilization method to stabilize the tracking platform. Furthermore, the servo system of the two-axis optoelectronic tracker was designed and used effectively.%载体平台摇摆对两轴光电跟踪仪光轴指向的扰动是制约光电跟踪仪跟踪稳定性和跟踪精度提高的关键因素.本文首先从控制原理出发比较了传统速率稳定方式与捷联稳定方式,然后针对两轴光电跟踪仪捷联稳定方式建立了扰动作用于光轴指向分量的数学模型,最后对某型光电跟踪仪采用了捷联稳定技术,并设计了相应的伺服系统,试验表明此系统设计合理,满足使用.
