The applications of web handling systems such as paper manufacturing, printing and film process, flexible component, paper manufacturing, textile.. are widely used in processing and manufacturing industry. In the application, tension control of the web plays a very crucial role. The mathematical model of the continuous web transport system is developed thanks to energy balance method. The paper presents a method of designing a tension control based on Linear Quadratic control. Several numerical simulation results are given to prove the effectiveness of the closed-loop system. In addition, the simulation results show incorrectness of another study in term of tension regulation.
