OPTIMUM FUZZY METHOD FOR CONTROLLING A RICE COOKER

An optimum fuzzy method applies a genetic algorithm to a fuzzy function which determines on the amount of rice and resolves switching patterns of a heater in a cooking cycle. The optimum fuzzy method controls a rice cooker by controlling the on/off times of its heater by the use of a fuzzy function in a cooking operation. The method includes: a step wherein experimental data is abstracted, and then is converted into desirable data to fit heating conditions; a fuzzy logic step in which the desirable data is divided into fuzzy areas, a fuzzy function is constructed according to the divided fuzzy areas, and an error value of the fuzzy function is produced after verifying the constructed fuzzy function; a comparison fuzzy function step in which the fuzzy function is applied to a microcomputer if the error value is within the range of the reference values; and a step wherein a genetic algorithm step is applied if said error value is not within the range of the reference values, and then said fuzzy logic step is returned to.
