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.

Tension Control System

Paper tension is the most important control parameter in roll material production that directly impacts the printing quality of the web offset. Based on the closed-loop paper tension control theory, by conducting a research into the simulation of paper tension control system with MATLAB/SIMULINK, presented the closed-loop control diagram about the paper tension control system. Under different control parameter, the value of the overshoot, respond speed and residual of the system varies. As a result, the quantitative research on the simulation of the system offers a valid means in improving the control accuracy.

Differential tensioning devices for belt conveyors in general and intermediate drives of extended conveyors in the form of closed traction loops are a new type of automatic tensioning devices that differ from other known designs by the presence of a stepwise discrete belt tension control system with separation of compensation functions for belt stretching under load and control of its tension during the operation of the conveyor in order to create optimal modes of belt loading. The article analyzes the well-known and practical concepts of belt conveyor control systems in general. The possibility of controlling the traction force realized by the intermediate belt drive by controlling the tension of the traction and load-carrying belts is shown. On the basis of the analysis, conceptual solutions for control systems for differential tensioning devices of belt conveyors are proposed with the possibility of both autonomous use and application in the structure of an integrated conveyor control system. Possible structures of linear parts of differential tensioning devices are presented, as well as options for the implementation of executive parts that directly move tensioning elements.
