Abstract: Aiming at the problems of the randomicity and instablity of the yarn tension in winding machine, a linear interpolation fuzzy controller was proposed based on a correction factor for the yarn tension control system. After the analysis of yarn tension control system、 fuzzy control system and linear interpolation algorithm, the relationship between fuzzy control system and linear interpolation was established. A method of linear interpolation fuzzy control for yarn tension control system was put forward. The simulation experiment of the yarn tension control system using Matlab was carried out, and the effect of the fuzzy control and linear interpolation fuzzy control on yarn tension control was studied. The research results show that compared with the classical fuzzy control, interpolation fuzzy controller essentially eliminates the steady state error and the chatter phenomenon of the system, simple and easy, and make the yarn tension control system is better, and has certain practical value.
