    • A complement to autotuning methods on PID controllers 

      Ferreiro García, Ramón; Pérez Castelo, Francisco Javier (International Federation of Automatic Control, 2000)
      [Abstract] This paper describes a complement to the autotuning ATV method. The proposed strategy is based in a frequency response design technique to get a three-term controller as a special case of a lead-lag design. The ...
