This paper introduces an advanced microcomputer controlled system of fiber winding tension （MCTS）, which realizes automatic control of fiber tension with high precision in fiber winding（FW） process. Adjusting fiber tension by means of exerting static-friction indirectly in FW process according to certain predetermined curve of tension change （namely, FW tension rule）, the system can control high tension of winding fiber precisely with little wear and tear to fibers. It has been proven that MCTS is stable and reliable and has good control performance. Comprehensive precision of control is within 3% and the maximum value of control tension reaches 55% of fiber strength. The system will achieve wider prospect in manufacturing field on high quality civil, military and aerospace FW products.
