基于FPGA的精跟踪控制系统的设计与实验

Design and experiment of the fine tracking control system based on FPGA

针对自由空间光通信精跟踪系统对小型化、智能化的要求,设计了一套以FPGA为处理核心的精跟踪控制系统,完成了对光斑的采集处理、补偿控制及相机的自适应控制等功能,并重点介绍了模糊自适应PID控制的原理及实现方法。最后,搭建了室内试验平台,对系统进行了评估。

In order to meet miniaturization and intelligent requirements of the fine tracking system in space laser communications, a set of fine tracking system was designed based on FPGA to complete the spot acquisition and processing, compensati on control, adaptive control of the camera and etc.The principle and implementation methd of a kind of fuzzy self-adaptive P1D was introduced. Finally, the indoor test platform was carried out to evaluate system.
