卷筒式冲击反循环钻机自动钻进的模糊控制

Fuzzy Control of Automatic Drilling of Drum-type Percussive Reverse Circulation Drilling Machines

摘要:

根据钻头下落的主要受力分析，给出了适用于模糊控制的下降时间估计模型。采用模糊控制方法控制卷筒式冲击反循环钻机自动钻进，可以迅速地跟踪破碎层变化引起的钻速变化。

Abstract:

Based on the analysis on the major dynamic force on the drill bit during it falling down, this paper presents a simple model of estimating the falling down time suitable for fuzzy control in the auto-drilling procedure. With the fuzzy control method used to control the auto-drilling procedure of the drum-type percussive reverse circulation drilling machine, it is possible to quick track the ROP change caused by the change of the drilled formation.
