On the other hand, quite a number of practical systems with numerous dimensions may have some fast variables taking on singular impulse characteristic, such as electric power system, control system of rolling mill assembly, biochemical process, nuclear reactor, control system of airplane and rocket, and chemical diffused reaction, etc. so, it is important to study the problem of robust control of singular system i n the domain of control theory
一般這些不確定性並非不可度量的，通常能給出這些不確定性大小的某種約束，魯棒控制理論正是處理系統模型具有不確定性的有效方法。另一方面，在大多數維數很大的實際系統中，都有呈現奇異攝動特性的快變變量，如電力系統，冷軋機的工業控制系統，生物化學過程，核反應堆，飛機和火箭系統，以及化學擴散反應等。 -
So the conceptions of " characteristic variable " and " characteristic model " are presented here, and with them as a clue, the paper focuses on collecting and summarizing the characteristic variable which can indicate system ' s state and performance, physical meaning of the variables are discussed also. the characteristic variable includes : stability - monitoring variable, characteristic variable based on time - domain performances, output waveform variable, parameter variable and circumstance variable
為此，本文提出特徵量和特徵模型的概念，並以此為思想主線，重點研究了能夠表徵系統性能的特徵量及其意義，引入了系統穩定性監控的特徵量、與控制指標相關的特徵量、輸出波形特徵量、參數特徵量及環境特徵量。 -
Based upon practical engineering applications, the variant separating - variable algorithms of hyper - surface fitting for arbitrary multivariate scattered data are presented by separating positional variables in a spatial domain from certain physical variables such as time, mach number, angle of attack and so on, followed by their comparison. when compared with existing scatted data interpolation algorithms, the new ones are more effective. a sufficient condition to exchangeable order of separation is obtained and order of continuity on the hyper - surfaces above is discussed
三、以實際工程應用為背景，將具有某種物理意義的量（如時間、 ma數、迎角等）與空間位置變量分開處理，給出任意散亂數據超曲面擬合變量分離的各種演算法，對它們進行了演算法的分析比較，獲得了分離次序可交換性的充分條件，給出了變量分離法構造的超曲面的光滑階。 -
