PURPOSE: To provide the analog/digital multicoupling fuzzy control system by reducing arithmetical loads at a CPU.
CONSTITUTION: This fuzzy control system is composed of plural control circuits 1 and 2 respectively composed of antecedent parts and consequent parts and provided corresponding to plural rules for fuzzy control, MAX circuit 3 to discriminate a maximum output value among the output values of the control circuits 1 and 2, and arithmetic circuit to perform non-fuzzy processing based on a synthetic waveform outputted from the MAX circuit 3, and the respective control circuits 1 and 2 are provided with first and second membership function generating circuits to generate membership functions shifted just for a prescribed amount respectively corresponding to the antecedent parts and consequent parts of the rules, and a MIN circuit 15 to discriminate a smaller output value between an output value outputted from the first membership function generating circuit corresponding to an output value from a sensor or the like and an output value repeatedly outputted from the second membership function generating circuit, and output the value from the MIN circuit 15.
