Abstract

Fuzzy reasoning methods have demonstrated their ability to solve different kinds of problems in various applications domains. Currently, there are various fuzzy reasoning methods and applications. This paper points out a kind of new recursive reasoning method which is based on move rate of fuzzy membership functions and it's application. To reduce the time cost by fuzzy reasoning, concepts of move rate and move action are proposed. In recursive fuzzy reasoning, generally, recursion is for consequent fuzzy sets, therefore fuzzy reasoning time is long and then practically programming workings is very difficult for us. Using new method, the designed system is composed of a block of PID operation, block of characteristic sampling, block of characteristic determine, block of PID parametric setpoint, block of fading factor calculation and control object. To determine PID parameters, fuzzy rules is made and proposed recursive fuzzy reasoning is applied. Finally, past method and proposed method is compared and PID parameter auto-turning simulation experiment results is explained.
