In order to enhance the tension control performance of the carbon fiber multilayer diagonal loom, twocontrol methods based on the yarn warping and the curling control are proposed. The tension control mathematicalmodels of carbon fiber multilayer diagonal loom, the yarn warping control model and the curling control model, arereestablished by the force analysis of the warping and the curling systems. Some technological process movements,such as the opening and the beating-up, are regarded as the disturbances. Based on the equivalent sliding modecontrol theory, the tension control strategies of the warping and the curling are constructed. Lyapunov method isused to prove the stability of the systems. Simulation results show that both the two methods could control thetension of the yarn, and the control results have good robustness to the disturbances.
