bottom blowing
解釋
底吹-
Nobody came near them, and their movements showed a mechanical regularity ; their forms standing enshrouded in hessian wroppers - sleeved brown pinafores, tied behind to the bottom, to keep their gowns from blowing about - scant skirts revealing boots that reached high up the ankles, and yellow sheepskin gloves with gauntlets. the pensive character which the curtained hood lent to their bent heads would have reminded the observer of some early italian conception of the two marys
沒有人走近她們她們的動作像機械一樣地一致她們站在那兒，身上裹著麻布罩衫這是一種帶袖子的黃色圍裙，從背後一直扣到下擺，免得讓風吹來吹去穿著短裙，短裙下面是腳上穿的靴子，靴子的高度到達了腳踝以上，手上戴的是帶有護腕的羊皮手套。 -

This thesis introduces the working principle, craftwork requirement, modeling process, control strategies and the realization of lf refining furnance bottom blowing argon control system. through the study and analysis of bottom blowing argon process control system, the thesis discusses the mean neural network model of controlled object and the mathematical models of the exectors, pwm adjustable pressure controller and pcm adjustable flux controller according to the relevant liquid knowledge and relevant data, including design data, test data and running data. to begin with the craftwork reguirement of bottom blowing argon and the actual instance of the control system, it presents the strategies of fuzzy parameters self - adaptive pid control used in pressure difference inner loop and fuzzy plus pi compound control used in flux outer loop which are based on the above modeling in order to carry out the accurate control of argon flux
本文介紹了lf精煉爐底吹氬過程式控制制系統的工作原理、工藝要求、建模過程、控制策略以及控制系統的實現。通過對精煉爐底吹氬過程式控制制系統進行研究與分析，並根據流體力學的有關知識以及有關數據（其中包括設計數據、試驗數據和運行數據） ，建立起了被控對象的平均神經網路模型和執行機構（即pwm調壓器和pcm調流器）的數學模型。在此模型的基礎上，從底吹氬工藝要求和控制系統的實際情況出發，提出了壓差內環模糊參數自適應pid控制策略和流量外環模糊pi復合控制策略，以實現氬氣流量的精確控制。 -
