• A bounded positive nonlinear PI controller for double-pipe heat exchangers 

      Zavala Río, Arturo; Astorga Zaragoza, Carlos Manuel; Adam Medina, Manuel; Brizuela Mendoza, Jorge Aurelio; Hernández González, Omar (2012)
      "In this work, temperature regulation of double-pipe heat exchangers is considered. The positive (unidirectional) and bounded features of the flow rate input variable are taken into account in the analysis. As a result, a ...
    • Reliable compartmental models for double-pipe heat exchangers: An analytical study 

      Zavala Río, Arturo; Santiesteban Cos, Raúl (2007)
      "In this work, the analytical properties of the heat exchanger infinite-dimensional dynamic model are discussed. More importantly, those of a 2nd-order lumped-parameter model using the logarithmic mean temperature difference ...
