First this paper describes the composing and technics of drillers ; then the composing of control system based on s7 - 300plc is described ; then thinking of such characteristics of oil driller as complexity and long delay, this paper brings forward the control strategy of combining the fuzzy control with smith estimate control algorithm, and sets down the way of auto - driller based on discal hydraulic pressure brake. at last the experiment based on matlab by computer shows that the effect of this control mode is very good and all performance are famous
首先本文闡述了鉆機的組成與工藝特點，然後描述了基於西門子s7 - 300plc的控制系統組成，然後針對傳統鉆機自動送鉆控制策略
落後的缺陷，同時考慮到鉆機的復雜性、大滯后等特點，提出了模糊控制演算法與施密斯（ smith ）預估控制演算法相結合的控制策略，給出了基於液壓盤式
剎車的自動送鉆智能控制策略， matlab的模擬實驗證明該控制方式控制效果良好，各方面性能指標都達到理想要求。

This machine adopts the best advanced imported frequency conversion timing controlled technical drive. it adopts dlectrical brake setting, its deendability is lofty and cutting is exact. this machine is mostly used for many quadrate foam rubber once flatly slicing. it can be continuously cutout, and do not recede cutter, the production efficiency is better
