Abstract
A control method for the rotational frequency of a weaving machine comprises the steps of performing a plurality of times of trial runnings of the weaving machine at different trial rotational frequencies to obtain the operating time for each rotational frequency, obtaining at least one indefinite coefficient in the formula representing the relation between a rotational frequency factor and an operating time factor by utilizing each obtained operating time and each trial rotational frequency, obtaining the optimum rotational frequency, at which the quantity of production reaches the maximum, on the basis of the obtained at least one indefinite coefficient and fuzzy inference, and controlling the rotational frequency of the weaving machine into the obtained optimum rotational frequency.
