The structure of the tension delivery system for a multi-functional NC winding machine, and the intelligent control of the winding tension for composite material tape were introduced. A practical tape delivery system was introduced and optimized, and its mathematical model was created. Based on improving the intensity and fatigue property of the winding products, the tension rule was introduced. The intelligent fuzzy PID control algorithm was introduced. Simulation shows that this algorithm for real-time correcting PID parameters is able to quicken the system responses, resist disturbances and improve the accuracy for the tape tension.
