Due to the nonlinearities and dynamical properties of multisection web machines, it is
essential to accomplish an appropriate mathematical model as well as design a compatible …

In this paper, a fuzzy disturbance observer and a high-gain disturbance observer based on a
variable structure controller are applied to deal with imprecise multi-shaft with web materials …

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 …

The speed and tension control problem of a web handling system is investigated in this
paper. From the system equations of motion, we developed a backstepping-sliding mode …

This study presents an adaptive controller for multi-span nonlinear web material linkage
systems with the characteristic of a variable moment of inertia and operating radius of rolls …

Solving unpredictable fluctuations in tension and speed is essential for optimizing the
material transportation process of web materials linkage systems. We develop an adaptive …

Web processing systems are very common in industry, however, controlling them is difficult
because of their nature such as multi-input multi-output, time variance, and nonlinearity. In …

Web transport system (WTS) is commonly used in the production and handling of web
materials such as paper, fabric, corrugated iron, steel, and printing operations. These …

A roll-to-roll system which is a flexible multi-shaft web transport system is very common in
the industries such as paper, metal processing, polymers, fabric and so on. However, web …

This article carries out research into an adaptive optimal controller for three-shaft web
machine systems to simultaneously regulate tracking problems and cost optimization. First of …
