Title: METHOD OF GENERATING FUZZY KNOWLEDGE BASE FOR A PROGRAMMABLE FUZZY CONTROLLER
Abstract:
A method of generating the knowledge base used for a programmable fuzzy controller comprising the steps of determining the relevant input and output 5 variables to be controlled; creating artificial potential fields for each of said variables; sampling each of said potential fields in order to generate fuzzy membership functions; compiling said fuzzy membership functions into fuzzy sets; and mapping inputs fuzzy set to output fuzzy sets through a rule base. The relevant input and output variables are including: minimum, maximum, 0 and equilibrium values; an importance weight; a non-linearity value; a control direction; and information as to whether said variable is an input or output variable. Further provided is a programmable fuzzy controller whose fuzzy knowledge base is obtained by the method described.
