摘要
简述了机载光电平台的工作原理与功能,介绍了平台速度环和跟踪位置回路的经典控制方法。从提高系统的跟踪精度出发,提出了复合控制在机载光电平台数引跟踪中的应用。介绍了前馈控制的原理和局限性以及在光电平台数引跟踪回路中的具体设计方法,并给出了实验结果。结果表明,与没有进行复合控制相比较,对机载光电平台实施前馈复合控制能够在不改变系统闭环稳定特性的前提下,将系统的数引跟踪精度提高10%。
The working principle and function of a photoelectric platform were introduced,and the classical control methods of the velocity loop and the position loop were also described. In order to improve the tracking precision of the system, a complex control in the digital-leading system of the photoelectric platform was put forward. The principle and limitation of the feed-forward control was introduced, and the design method of the feed-forward control in the system was particularly described. The experimental results show that the digital-leading tracking precision of the system is improved by 10% in the feed-forward control without changing the closed-loop stability of the system.
