      [Resumen] En este artículo se revisan las pautas para administrar los recursos de Fundation Fieldbus (FF) en la implementación de algoritmos de control de cara al aprovechamiento óptimo de los dispositivos basados en (FF)

    • Alternative to adjust the rule base on rule based controllers 

      Ferreiro García, Ramón; Pardo, Xoán C.; Vidal Paz, José (Pergamon, 2000)
      [Abstract] This paper describes a method to find a rule-base to be used on a rule based adaptive PID controller. A rule base is achieved by means of a direct method of fuzzy modelling by Takagi and Sugeno procedure by ...

    • Application of simulation to mechanical fault diagnosis by pattern matching with parity equations 

      Ferreiro García, Ramón; Pardo, Xoán C.; Vidal Paz, José (Universidade da Coruña, 1999)
      [Abstract] The operation of technical processes requires increasingly advanced supervision and fault diagnosis procedures to improve reliability, safety and global efficiency. Simulation associated to signal analysis ...
