Abstract
A control method for a weaving machine comprises the steps of obtaining the rotational frequency to be varied by the use of the fuzzy interference on the basis of the evaluation index representing the running condition level of the weaving machine, and then varying the actual rotational frequency of the weaving machine on the basis of the obtained rotational frequency. As the evaluation index, use is made of the control allowance level of the weaving machine, the quality allowance level of woven fabric, the working allowance level of the operator, the stop level of the weaving machine, the rate of a change value of the stop level to a variation value of the rotational frequency or the operating rate of the weaving machine.
