      Fuel cells are electrochemical devices with some internal variables that cannot be measured, but have to be monitored in real-time. That is the case for the liquid water inside the fuel cell catalyst layer. This motivates ...
    • Canceling output disturbances in observer design through internal model filters 

      Cecilia Piñol, Andreu; Astolfi, Daniele; Bin, Michelangelo; Costa Castelló, Ramon (2024-04)
      Article
      Open Access
      This work proposes a redesign method for nonlinear observers to reduce the effect of a particular class of output disturbances. Specifically, it is considered a disturbance composed of a term generated from a known system ...
    • LMI conditions for k-contraction analysis: a step towards design 

      Zoboli, Samuele; Cecilia Piñol, Andreu; Astolfi, Daniele; Serres, Ulysse; Andrieu, Vincent (2024)
      Conference lecture
      Open Access
      Recently, k-contraction has been proposed as a generalization of contraction properties for nonlinear time-variant systems. Existing tools for k-contraction analysis exploit complex mathematical tools known as matrix ...
