Abstract：The tension when coiling the optical fiber is the main factor in the qulity of optical fiber. The fiber material itself is smooth， easily fold and the transmission losses will be caused if the fiber tension over the limit.Therefore，in the process of optical fiber around，the fiber tension need to stable at a very small value. Aiming at  the characteristics of optical fiber around process， a new type tensioncontroller was designed, using C8051F340 as the core and based on the selfadjusting fuzzy PID. The requirements of precise control of optical fiber tension were satisfied. The results  of the actual control process show that， the selfadjusting fuzzy PID controller performance is  better than traditional PID controller in terms of stability and control accuracy，especially the robustness of the system.
