Aiming at such problems in combustion system of homemade middle and miniature boiler, as a complex system with the character of dead zone, time variation, serious non - linearity, large time delay, coupling and a lot of disturbance, this paper presents a new set of optimal control resources. by using well - matched control method on system, stable automatic running is realized. having the serious divulgence coals difference a lot from each other in character, instability of chemistry, value of lowest emission of heat, home - made boiler controller is not at all ideal. instead of traditional model that controls the ratio based on proportional control or with the correct signal of the amount of oxygen, this paper, combined with intellect control theory - - fuzzy control and self - optimizing concept, propounded a kind of fuzzy self - optimizing controller to be used in air supplying system of the boiler, and expatiates on the idea of dividing the control process into two parts, dynamic and static to realize, thus meets the demand of homemade boiler economic running
本設計針對國產中、小型電站鍋爐燃燒系統參數時變、嚴重非線性、干擾因素復雜、耦合嚴重、模型不易確定的特點，提出多變量協調控制方案，解決了系統可控性差，難以實現穩定自動運行的問題；在此基礎上，改變以往以煙氣含氧量控制送風的傳統模式，針對國產電站鍋爐設備主體及一、二次送風迴路泄露嚴重，煤種混雜、成分不穩定、燃燒發熱值低、燃燒效率不高等問題，應用智能控制理論中的模糊控制技術，結合自尋最優控制的思想，設計了一種模糊自尋優控制器，應用在電站鍋爐送風控制系統上，並闡述了動靜態兩種實現途徑，通過在線優化風煤配比，實現最佳經濟燃燒，切實保障了鍋爐的經濟運行。Therefore, the stator ground fault protection plays an important role in the protection system of generator. at present, the large - sized hydro - generators, such as the generators in three gorges power station, require that the stator ground protection must be with very high sensitivity, so that it is beyond the capacity of available protection schemes

論文首先從網路傳播的一般原理出發，探討廣告及網路廣告的含義、特徵、作用及分類等基本理論;其次分析了網路廣告中存在的主要問題，如網路廣告的立法缺陷問題、網路廣告不正當競爭問題、消費者權益損害問題等。其中重點闡述了網路廣告無法可依，擴大解釋不到位，管轄權難以確定等立法缺陷問題;網路誘餌與網路有獎銷售，網路關鍵字詞和鏈接技術，網站抄襲與不正常壓價等不正當競爭問題;以及網路廣告騷擾、侵犯隱私權、虛假與欺詐等損害消費者權益的網路廣告形式。Direct separation of co _ ( 2 ) from flue gas will lead to a reduction of power generation efficiency and an increase of power generation cost. the content of co _ ( 2 ) in flue gas is only about 3 - 15 %, which will lead to complicated separation process and high cost. this is because co _ ( 2 ) separation is very difficult from common flue gas, which has low co _ ( 2 ) concentration and high n _ ( 2 ) concentration at normal pressure
從鍋爐排煙中分離co _ 2將在一定程度上使電站效率降低，發電成本增加，其主要原因是燃煤電站鍋爐排煙中co _ 2濃度一般僅為3 15 ，在較低的壓力下從以氮氣為主要成分的混合氣體中分離較低濃度的co _ 2氣體的難度很大，從而導致分離設備復雜，成本較高。At present, the police in our country mainly through the " unit administration mode ", which merely emphasizes the administration of the website units, to execute this administration. however, with the rapid development of internet and expansion of its function, this administrative mode is under great impact, simultaneously, the police with the mode is challenged in terms of its management range, its administrative function, its management conception and so on. consequently, it inevitably results in some problems during the isa, such as blurring the borderline of the management, losing the balance of the role orientation and ignoring the importance of the people online
我們目前實行的是一種以網站提供單位為管理對象的「單位管理模式」 ，但隨著網際網路的高速發展和網路功能的大幅拓展，這一模式之下的公安機關的管理幅度、管理職能及管理理念等均受到了極大的沖擊，難以避免的出現管理邊界模糊、角色定位失衡、網上民眾邊緣化等弊端，加劇了網際網路上病毒與有害信息的傳播及涉網違法犯罪案件的上升，也致使網上警民關系的緊張和警力資源的嚴重不足。It is difficult to apply general pid control to temperature of secondary water of the heating power station with the indeterminate nonlinear and changing parameter characteristics by self - adjusting three parameters k _ ( p ) k _ ( j ) k _ ( d ) on line the fuzzy - pid controller has better response rate and stability property than the general pid controller
常規的pid控制難以滿足供暖熱水溫度控制要求。據此，本文提出了採用模糊pid演算法實現對熱力站溫度的控制，利用模糊推理對pid參數k _ p 、 k _ i 、 k _ d進行在線整定。The traditional pid control keeps its authority position. the inverted pendulum can stand for a long time using this method. but the parameters has many and are very difficult to be adjusted
傳統的pid控制仍然佔有權威的地位，由它控制的倒擺系統魯棒性也很好，並能長時間穩定站立，但參數確定很復雜，而且參數調節也很難，所以又採用了狀態空間法。Thousands of web sites provide the service of the geospatial information. although we have to encounter the fact that all those geospatial information can not work together, also it is hard to using our web browser to seamlessly read and access them. for business policy and data security, most of these data resources consist in legacy systems and isolated in desktop applications, it is hard to provide enough supports for spatial decision - making and sharing. furthermore from the geospatial information accessing to digital earth, the sharing of geospatial information is the core problem
但我們不得不面對這樣的一個現實：數以萬計的web站點之間無法很好地溝通和協作，很難通過瀏覽器訪問、處理這些分佈於web的海量空間數據；而且由於行業政策和數據安全的原因，這些空間資源大多是存於特定的gis系統和桌面應用中，各自獨立、相對封閉，從而形成空間信息孤島，難以滿足internet上空間信息決策所需的共享的需要。Our interest is in recognizing that ballistic missiles constitute a threat and weapons of mass destruction constitute a threat. over time, one has to recognize that it s every bit as important to us to be able to defend this piece of real estate, and our population in this location, as it is to defend our deployed forces, and to have our allies feel equally secure to the extent that s possible
