Title:
FUZZY CONTROLLER AND ITS OPERATING METHOD
Document Type and Number:
Japanese Patent JPH03144701
Kind Code:
A
Abstract:
PURPOSE:To attain rapid fuzzy inference processing by providing the fuzzy controller with a membership function memory for outputting a truth value corresponding to the input data supplied from an input register and an arithmetic circuit for executing fuzzy operation between plural truth values outputted from membership functions in each rule. CONSTITUTION:The codes of subrules are formed by using codes indicating the input variables of an antecedent part in each rule and codes indicating membership functions, then stored in a rule memory 21 in a fixed order. Then input data stored in an input register 22 are selected by the codes indicating the input variables included in the codes of the subrules. On the other hand, data indicating plural kinds of membership functions in each input variable are previously stored in the membership function memory 23 and one membership function is specified by the code indicating the input variable included in the subrule code and the code indicating the membership function. Thus, rapid inference can be attained.
