1. A method for the automatic generation of a multivariable fuzzy system from a sample set for use in a control system comprising the steps of: decomposing a sample set &Lgr; into a sample set cluster A&equals;&lcub;A {overscore (s)} &verbar;{overscore (s)}∈S&rcub;; calculating maximum error and total error; verifying that the maximum error and the total error are equal to or greater than respective threshold values; obtaining a fuzzy system for each variable; accumulating a final fuzzy system on the sample set &Lgr;; and applying the final fuzzy system to the control system.
