“…Based on this idea, a decentralised coordinated controller is designed in [18] by choosing suitable state variables of neighbour subsystems as coordination variables to reduce the effect of coupling exiting between subsystems. In [19], a decentralised coordinated control strategy without tension sensors is designed for elastic web-winding systems.…”

“…An ideal feedback linearisation control algorithm is used to decouple the tension and speed, which is composed of sliding mode speed controller and sliding mode tension controller. In literature [15], the winding equipment of three-motor is composed of several control subsystems, which interfere with each other. A decentralized coordinated control algorithm is designed to reduce the interferences between subsystems.…”

Tension is a key processing parameter in the process of composite fiber tape winding. The fluctuation of tension will affect the accuracy of winding and the performance of winding products, such as stress uniformity, fatigue resistance, strength, compactness and resin content. In view of the winding tension is time-varying and the application of tension needs to be more accurate, a tension calculation model is established. Due to the influence of dynamic performance of tension control system by cogging torque, inverter dead zone, ring gear clearance, friction torque, parameter drift, and measurement noise, an adaptive sliding mode control (ASMC) based on extended state observer (ESO) is proposed. The stability of the closed-loop system is proven by Lyapunov theory, the system state variables is estimated by ESO, and the input dead-zone is compensated by the designed adaptive law. Simulation and experimental results show that ESO-based ASMC improves the robustness and dynamic response performance of the tension control system, and can effectively suppress the chattering of the sliding mode control system. The void content and residual stress of composite products have been improved obviously. INDEX TERMS Composites tape winding, dynamics modeling, ESO, ASMC, tension control.

“…Hou [15] developed the nonlinear model of the webwinding system, two nonlinear observers with time-varying error dynamics are deduced from the presented model. Kang and Hou [16,17] respectively proposed cost-effective web tension controllers based on tension observers. However, the observers require precise mathematical model of the whole web handling machine.…”

Web tension and its distribution are key factors in the operation of web systems, the roll to roll (R2R) manufacturing of flexible electronics brings even higher requirements for it. To effectively get the web tension at any position on the R2R process line, a new web tension estimation method by measuring the local contact force is investigated in this paper, which can not only estimate the web tension, but also the web tension distribution. This study attempts to derive the approximate fitting formula between the local contact force and the web tension. Firstly, the schematic of web tension estimation method by local contact force measurement is presented; Then the mass spring model is used to derive the governing equations, which is discretized and solved by Improved Euler method. And approximate fitting formula of the local contact force with tension is derived based on the numerical results. Finally, to validate the fitting formula, the experiments are carried out to detect the local contact force and estimate both the web tension and its distribution.
