Fuzzy controller

Abstract

Abstract PURPOSE:To easily recognize an improper fuzzy rule by displaying a combination picture of an input variable label equivalent to a fuzzy rule and an output variable label on a display screen and also displaying the mark of the input variable value to the corresponding position of the displayed image in terms of change in the lapse of time. CONSTITUTION:A 1st display command means 2 is prepared to display a combination picture of an input variable label equivalent to a fuzzy rule and an output variable label on the screen of a display means 4. A position information generating means 2 produces the position information on the screen in response to the combination picture having the given input variable value. Furthermore a 2nd display command means 2 is added to display a mark having the given input variable value on the combination picture displayed on the screen in terms of change in the lapse of time based on the position information. That is, a combination picture of an input variable label equivalent to a fuzzy rule and an output variable label is displayed on a screen. Then a mark of the input variable value is displayed at the corresponding position of the picture interms of change in the lapse of time. As a result, the change in the lapse of time is easily and visually recognized for the input variable value. Thus an improper fuzzy rule can be easily decided.
