定標法則-
In the first part, the scaling rule for the hydrogenic impurity binding energy and the virial theorem value ( potential - to kinetic - energy ) in infinite quantum wells and quantum wires of rectangular cross - section with three different aspect ratios are studied through the variational method
在第一部分，利用變分法計算了無限深gaas矩形量子線和量子阱中類氫雜質束縛能的度規法則和維里定理值。 -
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。 -
