Abstract : we aimed at resolving a practical problem , i . e . the parameters in the process of oil dehydration and transpotation are coupling . for this purpose , the use of multi _ variables state feedback predictive control arithmetic to control the pressure and oil _ water interface system of free water dehydrator was studied . the result of control is satisfactory . the pressure and interface are stable , and the quality of dehydration is good 文摘:針對聯(lián)合站游離水脫除器脫水轉(zhuǎn)油過程中參數(shù)關(guān)聯(lián)嚴重這一實際問題,研究了將多變量狀態(tài)反饋預(yù)測控制應(yīng)用于游離水脫除器油水界面和壓力控制系統(tǒng),控制效果令人滿意,壓力、界面穩(wěn)定;脫水質(zhì)量合格
A new method to build the semi - quantitative system relating matrix was advanced , it was constructed via the dynamic envelopes , which were built by gm ( 1 , 1 ) based on the qualitative binning of observing data current of part variables , and its elements were calculated by the ratio of variable states ' corresponding areas in the dynamic envelopes 為了實現(xiàn)這一目標,一種新的系統(tǒng)半定量關(guān)聯(lián)矩陣的構(gòu)建方法被提出,它以系統(tǒng)部分變量觀測數(shù)據(jù)流的定性劃分為基礎(chǔ),應(yīng)用灰色gm ( 1 , 1 )模型建立其系統(tǒng)動態(tài)包絡(luò),并以動態(tài)包絡(luò)中變量各種狀態(tài)的對應(yīng)面積之比作為它們的關(guān)聯(lián)系數(shù)。
