ABSTRACT:
A fuzzy control method of a controlled object uses control rules, having a condition part, each condition part having both a first proposition characterized by a membership function whose variable is a time and a second proposition with respect to the state of the controlled object. According to the method, inputting information with respect to the state of the controlled object is input to a fuzzy control execution circuit. The degree of confidence of the first proposition characterized by the membership function is calculated according to the information for each of the control rules by using a particular equation. Then, the degree of confidence of the satisfaction of a condition part of each of the control rules is calculated according to the degree of confidence of each first proposition. A suitable control rule is obtained according to the degree of confidence of the satisfaction of each condition part so as to control the controlled object according to the control rule.
