Tension Control System

Through the in-depth study of working principle and application of PFC algorithm, the paper introduces PFC algorithm to the constant tension control of the system of shaftless driven in printer. In order to better implement constant tension control of shaftless driven control system, the paper choose a first order system as the transfer function of the system of tension model. The paper carries on the silulation of the system’s output of constant tension ,aiming at the situation of the changing of the internal parameters of prediction model for PFC algorithm, such as the attenuation coefficient of reference trajectory , the change of fitting points , prediction horizon and so on, matching of prediction model and tension model of PFC algorithm. The simulation system provides a theoretical basis to build the actual tension control system.

This paper presents a new constant tension control device which is suitable for warping of the carbon fiber or the flake yarns which are zero twist, high tensile strength, low shear strength, high specific modulus and self-lubrication and can meet the requirements of the warp tension of the carbon fiber multi-layer weaving equipment which is in the process of development. The device can make yarn tension consistent in warping process. Especially with the decrease of the diameter of yarn tube, the tension of yarn sheet is consistent in warping process. In the process of warping the warp doesnt twist and wear is small. The experimental results show that the mechanism can realize accurate control on the tension of the single yarn and the yarn sheet, and is able to meet the requirements of the warp tension of the carbon fiber multi-layer weaving equipment which is in the process of development.

Aiming at the problem of easy tensile deformation of PET film in production process of the energy-saving windows film, the paper presents control requirements of constant tension, constant line speed during the winding and unwinding. Firstly, the article gives a brief analysis of the tension cause and dynamics equation, and then establishes a mathematical model of the process of unwinding. Finally, starting from the model, the paper designed a control scheme to meet the constant tension, constant line speed using PLC and inverter technology. The field operation proves that the control system has achieved the expected effect of the control.Key words: Energy-saving Windows Film;Tension Control;PLC;inverter technology
