Tracking control and simulation of yarn tension based on right coprime factorization

In an actual weaving process,the yarn tension is changing,thus how to track and control it has become one of the most difficult problems. In order to reduce the tracking error of the yarn tension,and simplify the tracking control problem of the yarn tension,this paper puts forward a kind of control method of the yarn tension based on right coprime factorization. A rational yarn tension model is obtained by the mathematical calculation in combination with the theory of right coprime factorization and base on the three element model. Based on the yarn tension model,the tracking control method of the yarn tension is designed and proposed,and is proved by the simulation in Mat Lab / simulink. Through the design verification of theory and simulation system,the tracking control method based on the right coprime factorization can well implement the tracking and control of the yarn tension.
