The recognition circuit for EDM gap state is researched, selecting proper rate between nomal discharge, arc and blank, defining suitable servo feed.

研究了电火花放电间隙状态判别电路，选择恰当的正常火花放电、电弧放电及空载比例，确定较佳伺服进给量。

And adopting the method in which including periodical detecting and local detecting of gap discharge state, the servo feed control-system based on fuzzy control technology was designed.

在此基础上，采用控制周期总体间隙状况和局部短路的伺服控制策略，建立了基于模糊控制技术的回转式电火花展成加工伺服进给控制系统。
