PURPOSE:To obtain the programable membership of variable weight by being given the generating circuit of a weighting signal expressing the maximum value of a membership function and the weighting signal of the generating circuit. CONSTITUTION:A membership function circuit group 12 is provided with many membership function circuits of variable parameters. selects prescribed one or plural numbers of them in accordance with an input signal from a converting circuit 11 and outputs a signal expressing a membership function corresponding to the input signal. On the other hand, a circuit 15 generating one or plural membership functions is provided. The output of the membership function from the circuits 12 and 15 are calculated in accordance with a fuzzy inference and the calculation result is outputted. The output of a fuzzy logicalcircuit network 13 or a defuzification circuit 14 is compared with a reference input. A control/ storing circuit 16 is changed a parameter including the shape and weight of the respective membership functions so as to make the deviation to be zero in accordance with the result of the comparison. |
