Roll speed and web tension regulation using two degree of freedom control systems
(Oklahoma State University, 2015-06)
In this paper, we first consider the problem of load speed regulation in a two inertia system consisting of a motor shaft connected to the load shaft via a mechanical transmission. The problem is reminiscent of a material ...
Control of strip tension in the heating/cooling sections of continuous annealing lines using model-based tension estimation
(Oklahoma State University, 2015-06)
Continuous annealing lines are productive manufacturing lines used by steel making companies for the manufacture of thin steel sheet products. In these lines, the steel strip is continuously heated and cooled depending on ...
Design of tension control systems to minimize interaction and disturbance propagation in web process lines
(Oklahoma State University, 2015-06)
In roll-to-roll systems (R2R), a local controller is designed for each section or tension zone based on measurement of web tension and speed from that section; this is typically referred to as decentralized control. This ...
