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 ...
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 ...
