A Control Approach to Web Speed and Tension Regulation of Web Transport Systems Based on Dynamic Surface Control

[摘要] This paper proposes an approach to deal with control problems of unmodeled components of the web transport system. It is commonly challenging to construct model-based controllers to guarantee tracking quality due to the unknown terms in the mathematical model. Hence, our main contribution is to design a robust controller for the uncertain model of the web transport system based on Dynamic Surface Control (DSC) technique to ensure high accuracy in the tracking process of the web speed and tension. The proposed controller is designed in the face of the mathematical model of the web transport system that is adversely affected by bounded uncertainties. The stability of the controlled system is proved using the Lyapunov standard. The simulation results show the validity and the effectiveness of the proposed control law when the system is lack of system model’s information.
