      Open Access
      The aim of this paper is to give the conditions on the hysteretic Bouc-Wen model so that (i) it has the property of being bounded input bounded output (BIBO), and (ii) it dissipates energy (or is passive). This study leads ...
    • Causal canonical decomposition of hysteresis systems 

      Ikhouane, Fayçal (2020-10-01)
      Article
      Restricted access - publisher's policy
      Hysteresis is a special type of behavior found in many areas including magnetism, mechanics, bi-ology, economics, etc. One of the characteristics of hysteresis systems is that they are approximatelyrate independent for ...
