特征变数
Examples
- Intelligent pid control and fuzzy control are analyzed in point of characteristic variable , and two analytical structure of control based on characteristic model are summarized
本文剖析了智能pid控制和模糊控制等利用特征量进行控制的本质，并对基于特征模型控制的解析形式进行了探讨，总结出两类解析形式。 - Most of the current intelligent control methods are not based on system ' s mathematical - model , but they can control complicate system effectively , because they have got system ' s characteristic variable such as error and error derivative
目前出现的一些智能控制，之所以能在不依靠系统模型的条件下对复杂系统进行控制，其核心思想是基于系统的特征信息，例如误差和误差导数。 - In this paper , the near - infrared spectral measurement and principal component analysis ( pca ) of simulated spilled petroleum samples are made , the princpal component scores are taken as the cluster characteristic variables for making fuzzy clustering , the near infrared spectrometry and pca together with fuzzy clustering method are then used for rapid recognition of simulated spilled oils , and the sample clustering and recognition patterns are established
摘要对模拟溢油的石油类样品进行近红外光谱检测并进行了主成分分析，以主成分得分作为聚类的特征变量进行模糊聚类，采用近红外光谱测量结合主成分分析和模糊聚类法快速识别模拟溢油种类，并建立了样品聚类与识别模型。 - 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
为此，本文提出特征量和特征模型的概念，并以此为思想主线，重点研究了能够表征系统性能的特征量及其意义，引入了系统稳定性监控的特征量、与控制指标相关的特征量、输出波形特征量、参数特征量及环境特征量。 - By using the multi - linearity regression model and the non - linearity logit model on the 123 listed companies of china in 2002 respectively , this paper also documents : after controlling the firm characteristics variables , the corporate governance variable increases the explanation power of the multi - linearity equation and it is positively related to enterprise credit significantly ; in the non - linearity logit model , we find that corporate governance has different effects on the companies that own dissimilar credit ratings , the improvement of corporate governance will powerfully upgrade the enterprise credit especially when the company owns a lower credit rating
在实证方面,本文运用多元线性回归法与logit非线性法对我国2002年123家上市公司进行了实证研究:在多元线性回归法中,在控制了影响企业信用的企业属性变量的基础方程中加入公司治理变量,发现公司治理变量的加入有助于加大方程的解释力度,并且两者在统计意义上显著正相关,说明良好的公司治理能在一定程度上提升上市公司的信用水平;在logit非线性方程中,我们发现企业信用水平不同时,公司治理对上市公司企业信用的影响是不同的,尤其是当企业信用水平较低时,公司治理的改善能在较大程度上提高上市公司的企业信用。
