    • IconA mixed-signal fuzzy controller and its application to soft start of DC motors  [Presentation]

      Navas González, Rafael; Vidal Verdú, Fernando; Rodríguez Vázquez, Ángel Benito (Institute of Electrical and Electronics Engineers, 2000)
      Presents a mixed-signal fuzzy controller chip and its application to control of DC motors. The controller is based on a multiplexed architecture presented by the authors (1998), where building blocks are also described. ...
    • IconA modular CMOS analog fuzzy controller  [Presentation]

      Vidal Verdú, Fernando; Navas González, Rafael; Rodríguez Vázquez, Ángel Benito (Institute of Electrical and Electronics Engineers, 1997)
      The low/medium precision required for many fuzzy applications makes analog circuits natural candidates to design fuzzy chips with optimum speed/power figures. This paper presents a sixteen rules-two inputs analog fuzzy ...
    • IconA modular programmable CMOS analog fuzzy controller chip  [Article]

      Rodríguez Vázquez, Ángel Benito; Navas González, Rafael; Delgado Restituto, Manuel ; Vidal Verdú, Fernando (Institute of Electrical and Electronics Engineers, 1999)
      We present a highly modular fuzzy inference analog CMOS chip architecture with on-chip digital progranirnability. This chip consists of the interconnection of parameterized instances of two different kind of blocks, namely ...
    • IconCMOS design of adaptive fuzzy ASICs using mixed-signal circuits  [Presentation]

      Vidal Verdú, Fernando; Navas González, Rafael; Rodríguez Vázquez, Ángel Benito (Institute of Electrical and Electronics Engineers, 1996)
      Analog circuits are natural candidates to design fuzzy chips with optimum speed/power figures for precision up to about 1%. This paper presents a methodology and circuit blocks to realize fuzzy controllers in the form of ...
    • IconLearning under hardware restrictions in CMOS fuzzy controllers able to extract rules from examples  [Article]

      Vidal Verdú, Fernando; Navas González, Rafael; Rodríguez Vázquez, Ángel Benito (Universidad de Granada. Departamento de Ciencias de la Computación e Inteligencia Artificial, 1996)
      Fuzzy controllers are able to incorporate knowledge expressed in if-then rules. These rules are given by experts or skilful operators. Problems arise when there are no experts or/and rules are not easy to find. Author's ...
    • IconMixed signal CMOS high precision circuits for on chip learning  [Presentation]

      Vidal Verdú, Fernando; Navas González, Rafael; Rodríguez Vázquez, Ángel Benito (Institute of Electrical and Electronics Engineers, 1998)
      Learning algorithms have become of great interest to be applied not only to neural or hybrid neuro-fuzzy systems, but also as a tool to achieve a fine tuning of analog circuits, whose main drawback is their lack of precision. ...
    • IconMultiplexing architecture for mixed-signal CMOS fuzzy controllers  [Article]

      Vidal Verdú, Fernando; Navas González, Rafael; Rodríguez Vázquez, Ángel Benito (Institute of Electrical and Electronics Engineers, 1998)
      Limited precision imposes limits on the complexity of analogue circuits, and hence fuzzy analogue controllers are usually oriented to fast low-power systems with low-medium complexity. A strategy to preserve most of the ...
    • IconNeuro-fuzzy chip to handle complex tasks with analog performance  [Article]

      Navas González, Rafael; Rodríguez Vázquez, Ángel Benito; Vidal Verdú, Fernando (Institute of Electrical and Electronics Engineers (IEEE), 2003)
      This Paper presents a mixed-signal neuro-fuzzy controller chip which, in terms of power consumption, input-output delay and precision performs as a fully analog implementation. However, it has much larger complexity than ...
