    • Design of fixed structure controllers for web tension control 

      Pagilla, P. R.; Cimino, M.; Knittel, D. (Oklahoma State University, 2007-06)
      It is a common practice in industry to design a Proportional-Integral (PI) velocity feedback controller cascaded with a PI outer tension loop to regulate web velocity and tension to their desired values. The controller ...

    • Lateral control of a web using estimated velocity feedback 

      Pagilla, P. R.; Dwivedula, R. V.; Zhu, Y. L.; Mandal, S. S.; Hopcus, K.; Haque, J. (Oklahoma State University, 2001-06)
      The focus of this paper is on lateral control of a web using estimated motor velocity feedback. A reduced state velocity observer is designed to estimate the motor velocity based on the measured lateral position of the web ...

    • Modeling of laminated webs 

      Pagilla, P. R.; Reid, K. N.; Newton, J. (Oklahoma State University, 2007-06)
      A dynamic model of the longitudinal behavior of a laminated web is developed. A single web model that takes into account both thermal and hygral strains is developed first from first principles; the model assumes heat ...

    • Role of active dancers in tension control of webs 

      Pagilla, P. R.; Perera, L. P.; Dwivedula, R. V. (Oklahoma State University, 2001-06)
      This paper investigates the role of active dancers in attenuation of web tension disturbances in a web process line. A general structure of the active dancer is considered; an input/output model is developed for analysis ...
