Abstract: This paper introduces the affixture machine tension control and its postulate.Since the affixture machine is a typical complicated,tandem driving,time changing and non-linear winding system,it is rather difficult to control constant tension.The traditional proportional-integral-differential (PID) controller can not meet the requirements,thus,a fuzzy adaptive PID tension controller is proposed for effective settlement of the problems of dynamic change of the non-linear system and the establishing of mathematic model.Through comparing the simulated curve of fuzzy PID with that of traditional PID,it can be seen that the fuzzy PID controller has better adaptability to the change of the winding radius than the traditional one.
