The general scheme of high tension control system is introduced. A fiber high winding tension control system was designed,with a set of the magnetic powder brake as the actuator, with tension sensor of fiber ribbon tension real-time monitoring as feedback element, and setting the tension control allocation scheme to adjust the tension of a closed-loop control system.The mathematical model was established, while the way to design hardware and software platform of the tension control system.Study works on constant tension, tension step response were carried out separately base on the proposed platform. Experimental results show that the proposed tension control system responses fast and the tension fluctuation rate is low，which can satisfy the requirements of the high tension control for fiber winding．
