【正文】 design with this. This kind of method and farmland methods pare Lie in it and don39。 Can also use the random manhunt method etc.. (3) Control the conditional design: A method of farmland is under the condition of have no stipulation Usage of, if the existence control, can make use of to control to search the method, will control to turn at first Change for all rate form. Another method is an usage definition the method of the boundary, settle a Divide a function. Can also use the Monte2 Carlo method to solve. Cultural heritage[2] pointed out a method of farmland at handle to control and many target problem square Shortage of face, developped a method of farmland, make it be able to handle to control and many target of usage in text statisticses the analytical ANOVA concept to certain excellent turn the target The importance of each factor in the function, expeled the influence of the of no account factor, get only An of can go the superior solution. Cultural heritage[3] make use of monotonous sex analysis technique and will have the haleness of the stipulation successfully Sex design problem simplification for have no control excellent turn the problem, let up the amount of calculation with this. Text Dedicate[4] put forward an according to analytical method of monotone, solve or help to solve Following problem: Find out the design changes the value of measure the x, make can39。 Turn to design the method, is a kind of to fix attention on in the economic performance, have a foothold in the technical quality of engineering Quantity design and management technique .This kind of design method designs the square in the traditional engineering Development on the method since then of, it develop process is: Mathematics is excellent to turn → the engineering is excellent to turn( try Check the design) → a method( the Tagnch imethod) of farmland → strong design. The strong design can resolve the largescale product design problem. It strengthened the farmland The system design of the method, outstanding the QDF( the quantity function launch) leads to make first se. 1. 3 halenesses design the improvement of method (1) Different form of the indetermination factor: A method of farmland considered only random Indetermination factor. Cultural heritage[1] discussed theindetermination factor of other forms, and point A these factors to excellent turn the target and the quantity letter to pare to have the influence, thus improved S. The N expression type. (2) Other manhunt method: A method of farmland uses to experiment the method only at whole The design carries on the manhunt in the space, experimenting through just hand over of a series, can select Superior design parameter. What a method of farmland use is 23 the numbers experiment the design Method, it improves the method: Use two enter the type manhunt。 Satisfy to produce The article calculator of the overall quantity index sign gather turn the intelligence design。 The structure control integral whole turn ; Lead the speech At the machine system design pletes but enters the manufacturing and uses the stage, because of The influence of a series of indetermination factor, may appear the function up the big variety, very Go to make product expired, thus cause the quantity unsteady .How make design to produce The article has the haleness, that is make the product and processes have the outside interference of holdout lead Quantity of rise the ability of the motion, design the front of method to follow the topic current. Lift from here The machine concept of the strong sex design. 1 according to strong design of the quantity engineering 1. One quantity engineering The quantity engineering( the Q E) develops the whole process quality control and quantities to the product The system engineering method of the control, include to design the total quantity engineering and the manufacturing quantity works Distance. Design the quantity engineering to mainly have: Strong sex design。 Quantity engineering。 robust structure。 第 頁 共 61 頁 8 According to the machine design method of the haleness Abstract: The concept of robustness derived from the field of cont role Engineering and cont role theory, and the concept of robust design put for ward by Taguch and used in quality engineering get into the area of mechanical engineering in recent years. In this paper we discuss four aspects of the problem: robust design based on quality engineering。 如何把控制中的魯棒性和機(jī)械結(jié)構(gòu)的健壯性有機(jī)地結(jié)合起來 ,是理論研究的重點(diǎn)所在。尤其是在當(dāng)前各 學(xué)科互相滲透、互相補(bǔ)充的情況下 , 機(jī)械的健壯性和結(jié)構(gòu) .控制一體化健壯設(shè)計(jì)是這一領(lǐng)域的前沿課題。 (4) 健壯性的概念起源于控制 (魯棒性 ) , 后逐漸引入質(zhì)量工程 , 現(xiàn)已向機(jī)械工程滲透。適用面較窄。今后主要工作 在于提出更有效的健壯設(shè)計(jì)方法。 5 結(jié)束語 (1) 基于質(zhì)量工程的健壯性設(shè)計(jì) , 可以稱之為“廣義”的健壯性設(shè)計(jì)方法 , 主要是在設(shè)計(jì)中對(duì)機(jī)械結(jié)構(gòu)在制造中產(chǎn)生的偏差加以克服 , 使產(chǎn)品具有抵抗制造誤差干擾的能力。 (4) 控制系統(tǒng)能量。 (2) 性能魯棒性 。文獻(xiàn) [22 ]同時(shí)考慮這兩種魯棒性 , 用閉環(huán)系統(tǒng)特征值矩陣的狀態(tài)數(shù)來反映穩(wěn)定性魯棒性 , 以相關(guān) 靈敏度來示性能魯棒性。 以往對(duì)穩(wěn)定性魯棒性的研究主要在頻域中用單值分解來完成 , 而對(duì)性能魯棒性的研究則用靈敏度分析在時(shí)域進(jìn)行。反饋控制系統(tǒng)的魯棒性成為設(shè)計(jì)中的一個(gè)重要問題。結(jié)構(gòu)參數(shù)中也存在著相當(dāng)?shù)牟淮_定性 , 這些不確定性會(huì)明顯地影響控制系統(tǒng)的穩(wěn)定性和性能特性。 文獻(xiàn) [22 ]較深入地討論了具有主動(dòng)控制的結(jié)構(gòu)的健壯設(shè)計(jì)問題 , 指出柔性結(jié)構(gòu)從本質(zhì)上講是分布參數(shù)系統(tǒng)。求解多目標(biāo)優(yōu)化問題一般的是用加權(quán)因子將各目標(biāo)線性組合到一個(gè)目標(biāo)中 , 但這樣會(huì)導(dǎo)致求出的解不一定是全局最優(yōu)解。多目標(biāo)優(yōu)化問題的難點(diǎn)在于幾乎不存在一個(gè)解使所有目標(biāo)函數(shù)同時(shí)達(dá)到最優(yōu)。 第 頁 共 61 頁 6 文獻(xiàn) [ 21 ]討論了結(jié)構(gòu)和控制的集成設(shè)計(jì) , 設(shè)計(jì)的對(duì)象是一具有主動(dòng)控制的結(jié)構(gòu) , 約束施加于閉環(huán)系統(tǒng)的阻尼參數(shù)上。這樣導(dǎo)致的結(jié)果是無法考慮兩個(gè)系統(tǒng)的耦合 , 使得系統(tǒng)參數(shù)間相互干擾 , 設(shè)計(jì)出的結(jié)果可能效果很差。所以對(duì)于結(jié)構(gòu) .控制一體化的健壯化性設(shè)計(jì)的研究 , 具有重要意義。 4 對(duì)結(jié)構(gòu) .控制一體化的健壯性研究 現(xiàn)代機(jī)械工程技術(shù)發(fā)展到今天的水平 , 已不再局限于某一領(lǐng)域。 文獻(xiàn) [19, 20 ]討論了模糊健壯結(jié)構(gòu) , 指出以前都是以靈敏度的方法來設(shè)計(jì)健壯結(jié)構(gòu)的 , 但靈敏度僅僅提供了局部信息 , 因此不能確定用靈敏度設(shè)計(jì)出的結(jié)構(gòu)在大的范圍內(nèi)具有健壯性。 文獻(xiàn) [ 18 ]將健壯結(jié)構(gòu)從靜態(tài)延伸到動(dòng)態(tài) , 提出了廣義的動(dòng)態(tài)健壯結(jié)構(gòu)的概念和廣義動(dòng)態(tài)健壯結(jié)構(gòu)的設(shè)計(jì)方法。還應(yīng)用廣義的健壯結(jié)構(gòu)概念 , 進(jìn)行了算例分析 , 得出的結(jié)論為 : 廣義健壯結(jié)構(gòu)用于靜態(tài)問題中的大部分問題都很有效 , 但些性能指標(biāo)的效果欠佳。他們提出的健壯結(jié)構(gòu)的定義是 : 不管結(jié)構(gòu)內(nèi)部參數(shù)還是外部環(huán)境的變動(dòng) , 都對(duì)結(jié)構(gòu) 的影響達(dá)到最小 , 并提出了健壯結(jié)構(gòu)設(shè)計(jì)問題的格式。文獻(xiàn) [15 ]提出了應(yīng)用試驗(yàn)結(jié)果和定性靈敏度來對(duì)實(shí)際的設(shè)計(jì)對(duì)象進(jìn)行定性優(yōu)化設(shè)計(jì)方法 , 使設(shè)計(jì)結(jié)果具有健壯性。爾后又將這種算法推廣到多目標(biāo)優(yōu)化 , 第 頁 共 61 頁 5 并 義了三種模糊語言“小” ,“標(biāo)準(zhǔn)”
