Abstract
A fuzzy logic system and method for controlling a plant in accordance with fuzzy logic processing using data representing fuzzy logic rules and membership functions includes elements and steps, respectively, for performing fuzzy processing (i.e. antecedent processing, rule evaluation and neural defuzzification) of a plant control signal to control a plant (e.g. servomechanism) and adjusting the membership functions based upon differences between desired and actual performance criteria for the plant being controlled.
