基于模糊线性判别分析的控制规则约简

Rule Reduction Based on Fuzzy Linear Discriminant Analysis

在线性判别分析的基础上提出了一种模糊线性判别分析方法,对模糊数据进行判别分析,并将这种方法应用于模糊化控制器的规则约简,从而在不影响控制品质的基础上,减少控制器运算量.实验表明,经过规则约简之后的模糊控制器能够顺利完成倒车控制,具有较高的普适性.

This article proposes a Fuzzy Linear Discriminant Analysis method,so that it is applicable in situations where fuzzy data are provided.In some cases of fuzzy control,this method can greatly reduce the rule base dimension of fuzzy controllers,while remaining the control quality almost unchanged.Simulation experiments for the truck backer-upper problem validate the efficiency of the proposed method.
