摘要
分析光电编码器四倍频原理,提出了一种基于可编程逻辑器件FPGA对光电编码器输出信号倍频、鉴相、计数的具体方法,有利于提高被控对象的测量精度和控制精度。
This article researches on the incremental opto-electric encoder and analyze its fourfold frequency multiplication principle, it gives a method based on FPGA to multiply the signal of the incremental opto-electric encoder, differentiates its phase and counts its number, the controled object＇s precision of measure and control can be heightened.
