Because central potentials of four y windings in 12 - phase generator are not equal each other and there is no common reference inside the generator, it is difficult to identify the on / off of rectifying elements. in this paper, by using a mathematical model with line voltage substitute for phase voltage, the problem that there is no common reference in the 12 - phase generator with rectifier is solved. based on results of the studies on small prototype, 920kw charging generator applied in a submarine is improved in design, and therefore power oscillation with high magnitude when two generators are operating in parallel
由於十二相發電機中四個y繞組的中點電位不等，電機內部沒有公共參考點，從而在判斷整流元件導通時，不能象三相同步發電機整流系統那樣認為陽極電位最高或陰極電位最低的整流元件導通，本文採用了以線電壓代替相電壓建立十二相整流發電機的數學模型，從而解決了十二相發電機無公共參考點的問題。 -
Topographical maps are the principal frame form of gis, and realization map digitizing and offering gis basic spatial data is one of the important research fields in surveying and gis, which is also necessity of development of science and technology. based on building gis - oriented topographical mapping system theories, this themes apply the advanced objectarx technology, aim at topographical mapping and exporting to gis, and resolve several key problems, such as symbols analysis and building, dtm and contour line automatic drawing, topographical map adjoining, digital image rectifying etc. and it offers models and arithmetic, realizing the general functions of gis - oriented topographical mapping system
本文以建設面向gis的測量繪圖平臺理論為基礎，以autocad平臺下objectarx開發技術為核心，圍繞地形圖的成圖和入庫（ gis數據庫）這一課題，對其中的關鍵技術難題? ?符號庫的建立與實現、 dtm與等高線的自動繪制、地形圖接邊、數字化柵格圖像的定向與糾正、介面數據文件的生成等進行了研究分析，提出了相應的模型和演算法，實現了面向gis的測量繪圖系統的基本功能。 -
This paper focuses on the research of fuzzy control, especially rule self - adjusting fuzzy control method. by theoretic analysis and simulations, the influences of parameters and system performance characteristic of some kinds of rule on - line self - regulating fuzzy control methods are discussed, and a novel real - time self - adjusting fuzzy control method ( vsrsafc ) is proposed from the diagrammatic point of view. in vsrsafc, the slope of the rectifying curve of rule scaling factor a is altered by the fine - tuning and coarse tuning combined mechanism to adjust the fuzzy control rules according to error e and error change ec, which more coincides with characteristic of system response than the conventional self - adjusting method that adjusts rule scaling factor only according to the error e, and has better static and dynamic performances than the latter
其中變斜率規則自調整模糊控制的效果較為明顯，它是基於插值的非線性規則自調整模糊控制的引申以及常規全論域規則自調整模糊控制的改進，該方法採用粗、細調結合機制，通過改變規則調整因子的修正曲線斜率，使系統同時根據誤差e以及誤差變化ec在線調整模糊控制規則，比傳統的僅基於系統誤差e的自調整方法更符合系統響應特性，可獲得更好的動靜態控制性能，特別是對于系統參數發生改變、控制參數選取不當等不良狀況，控制器仍能較快自調整，具有較強的在線自適應能力。
