    • openAccess   Frequency-dependent approach to model validation for iterative identification and control schemes 

      Balaguer, Pedro; Vilanova, Ramon Institution of Engineering and Technology (2009)
      Classical validation methods “accept” or “reject” a model as a valid representation of a plant for some intended use. However this binary result has several problems as firstly, models are neither good nor bad but have ...

    • openAccess   Fuzzy discretization and control for non-linear, multiple binary input systems 

      Ariño, Carlos; Mas Torres, Lluís; Balaguer, Pedro Elsevier (2023)
      The control of continuous-time linear systems with binary inputs cannot benefit from existing control design techniques because they are based on continuous control actions. In particular, optimal control problems with ...
