Abstract
A control apparatus of an electrical appliance comprising a sensor for detecting a physical amount; and a fuzzy inferring device for determining the drive condition of a load by fuzzy inference based on a signal outputted from the sensor, and wherein the sensor has at least one normalized membership function to be used by fuzzy inference and achieves a plurality of membership functions which can be expressed by congruent curves by performing a predetermined subtraction or an addition on the signal outputted from the sensor.
