Overlapping Decentralized Controller Design for Web Tension Control System

Importance of Overlapping Decomposition for a Web Tension Control System

Abstract: The increasing requirement on the control performance for systems handling web material led to investigation for sophisticated control strategies. Actually many industrial web-transport systems use decentralized PI-type controllers. But when decentralized control is applied to a web tension control system, the interactions among control stations are the major problem for the controlle...

Self-Tuning PI Control Using Adaptive PSO of a Web Transport System with Overlapping Decentralized Control

Web transport systems for transporting films, textile material, paper, etc., are usually large-scale systems. The velocity and the tension of the web are controlled by dividing the systems into several subsystems in which strong coupling exists between the velocity and tension control. A self-tuning PI (STPI) controller with an estimator based on a novel adaptive particle swarm optimization met...

Decentralized Control Design Using a New Approach of Longitudinal Multi-overlapping Decomposition Strategy: Application to Web Winding System

Industrial systems are generally characterized by their complication which is essentially caused by the large number of variables exist in such systems, and also the overlapping structure of information coming to or going from it. This complication can afford loss of some important parts of information, in addition to making study of these systems, if not impossible, at least very hard for rese...

Decentralized Overlapping Control for Civil Structures

This paper presents the problem of overlapping decentralized control design for a 20-story building benchmark which was proposed by the ASCE to the structural control community to compare different control design methods. The control design problem is focused on an in-plane (2-D) analysis and synthesis of one-half of the building structure. This naturally suggests the overlapping decomposition ...
