1. An analog fuzzy logic controller implementing a set of fuzzy rules with which are respectively associated output values expressed as many polynomials, the coefficients of said polynomials having predetermined values specific to the different rules, and each of said rules including at least one condition consisting of a fuzzy relationship between one of said input variables and a reference value, said controller comprising first means for determining the weight of each of the fuzzy rules, said weight being determined by combining results of comparison of the values of the input variables with the reference values in the different conditions of said rule; wherein said controller further comprises: second means for estimating a global value for each of said coefficients, said global value being determined by starting from the different values of said coefficient in the different rules and taking into account said respective weights of said rules, and third means for delivering, as output of said controller, the value of a polynomial in said set of input variables, the coefficients of said polynomial being said global values delivered by said second means.
