摘要

模式识别调优的基本出发点是

以工艺参数为特征变量构筑模式空间

按调优目标划分样本的类别.采用模式特征抽提方法压缩工艺参数

找出影响目标的主要因素.分别对两类调优问题

即最优指标问题和最优方向问题

提出了寻找最优工况的具体处理方法.对多目标调优也作了简单的讨论.

Abstract

Pattern recognition method has been applied to solving the problems of the optimization of chemical processes. The basic starting-point of optimization by pattern recognition is that the technological parameters are used as feature variable to construct the pattern space and all samples are divided into a number of classes according to the production target to be optimized. In order to find out the key factors influencing the target

the method of feature extraction is adopted to reduce the dimensionality of the pattern space of technological parameters. Some specific methods are suggested to search for optimal production conditions for two kinds of optimization problems

i. e.

the problem of optimal index and the problem of optimal direction

respectively. The problems of multiple targets are also discussed briefly. The methods of process optimization by pattern recognition have been applied to some factories and considerable technical-economic benefits have been achieved.
