用互协方差分析法整定模糊控制器比例因子

NOVEL TUNING METHOD OF SCALINGFACTOR IN FUZZY CONTROLLERS

提出了模糊控制器比例因子的另一种整定方法。此法基于平稳过程中最佳整定比例因子应满足一种特定的统计输入输出关系的假说。对统计关系的度量即是相关函数和相关系数。借助于单输入单输出系统讨论使用互协方差函数整定比例因子的方法。

The paper deals with the optimal adjustment of scaling factors in Fuzzy Controllers. The method bases on the assumption that in the stationary case an optimally adjusted scaling factormeets a specific statistical input output dependence. A measure for the strength of statistical dependence is the correlation function and the correlation coefficient,respetively.The adjustmen t of scaling factors using correlation functions is POinted out by means of a Single input-Single Output(SISO)system.
