“…Several control strategies based on decentralized or centralized multivariable control sctructure have been suggested for winding and web transport systems in order to achieve the control objectives, such as : PID [1] [2], loop shaping [3], gain scheduling [4], µ-analysis [5], multivariable H ∞ control [6]. It led also to the investigation for advanced control strategies including : fuzzy logic [7], neural networks [8], optimum control [9] and robust control [10] [11].…”

In winding and web transport systems, which are complex and large scale interconnected dynamics systems with a demand for increasingly high level of performance, the objective is to ensure quality processing and rewinding of the product. A major problem in controlling such systems is that disturbances propagate through the system and affect both velocity and tension loops because of the strong mechanical couplings. An active disturbance rejection control (ADRC) strategy and a nonlinear PI (NPI) controller are proposed and compared with PI control to improve the overall performance of the system, i.e. increasing dynamic tracking precision, reducing rise time for step input and furthermore improving robustness to the change of the web stiffness during the winding process. Simulation results of an industrial application show the effectiveness and disturbance rejection properties of the proposed controllers in coping with large dynamic variations commonly seen in web handling applications.

“…A review of the web tension control problems can be found in [3]. Fuzzy logic [4] [5], neural network [6] [7], optimal control [8], nonlinear sliding mode [9], control active disturbance rejection control (ADRC) strategy [10] [11], and robust control approaches [12] are used. Robust Lyapunov-based feedback control [13] and multivariable H ∞ controller has been proposed for industrial web transport systems [14] [15].…”

Many types of materials are manufactured or processed in the form of a sheet or a web (textile, paper, metal, etc.), which then couples the processing rolls and the associated motor drives. In Winding and web transport systems, the main concern is to control independently speed and tension in spite of disturbances such as radius variations and changes of set point, and to the coupling introduced by the elastic web. So the increasing requirement on the control performance led to investigation for sophisticated control strategies. To improve the overall performance of the winding system, we propose to apply decentralized control based an Integrator Backstepping strategy for controlling web winding systems. The advantage of this type of control is to impose stability properties by building recursively a Lyapunov function for the overall cascade system. Our winding system is simulated in Matlab /Simulink T M environment, the results obtained illustrate the efficiency of the proposed control, with no overshoot, and the rising time is improved with good disturbance rejection comparing with the classical control law (PI controller).

“…There are many sources of velocity disturbance: roller noncircularity, web sliding… Due to the elasticity of the web, these disturbances are transmitted to the web tension. Several studies concerning web handling control [1] [2] [3] generally use PID, fuzzy or neural approaches. Multivariable control strategies recently have been proposed for industrial metal transport systems [4] [5], and the decoupling of web tension and velocity with H ∞ robust control was presented in [6] [7].…”
