Fuzzy inference device

Abstract

Abstract PURPOSE:To easily recognize improper rules by calculating the antecedent part conformity related to an input part with time and differentiating this antecedent part conformity with time to calculate and display the change rate of the antecedent part conformity. CONSTITUTION:A CPU 2 of a control part 1 performs the fuzzy inference operation and controls the operation of a CRT 4 as the display command means and functions as a means which calculates the antecedent part conformity with time and a means which calculates the change rate of the antecedent conformity. An operator inputs membership functions and fuzzy inference rules from a keyboard 5 while confirming the display on the CRT 4, and membership functions and fuzzy rules based on input values are stored in a memory 3. Sensors (a) of a control object device A calculate the antecedent part conformity of each rule with time at the time of input and differentiates it to calculate the change rate of the antecedent part conformity and displays this change rate on a CRT with time. Thus, improper rules or the like are easily recognized.
