This design is a basic method for testing spring fan wheel assembly and steel cable tension control system. PLC is used as logic control core. Stepping motor and magnetic powder braker is used as an executive element. The constant tension control of the running process of the system is completed. The fuzzy control process of PID system includes two parts of tension loading and damping loading. The method of modular software is used to make the program structure clear.

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.

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

This paper does some researches on the framework and control mechanism of traction and take-up system of Loom, which keep the winding tension constant. A traction and take-up control model using fuzzy neutral network adaptive PID algorithm is designed. The results prove this model is available in constant tension control system. The constant tension control system makes traction and take-up system operate more precisely and improves the quality of fabric.

Winding tension is one of the most important factors that affects the winding products' quality. This paper introduces a method to develop tension control system based on data acquisition card, and presents the block diagram of the system which actuators are AC servomotors. In order to meet the demands on tension control system, such as good stability, strong robust and etc., this paper proposes a tension control method which is based on the fuzzy control theory.
