• openAccess   Improving the identification from relay feedback experiments 

      Miguel-Escrig, Oscar; Romero Pérez, Julio Ariel Elsevier (2022-01)
      This paper proposes a new method for systems identification from relay feedback test. As a difference with most of the existing methods, which are based on the describing function technique, our proposal considers a more ...
    • closedAccess   PI and PID auto-tuning procedure based on simplified single parameter optimization 

      Romero Pérez, Julio Ariel; Sanchis LLopis, Roberto; Balaguer, Pedro Elsevier (2011)
      In this paper a new auto-tuning algorithm for PI and PID controllers based on relay experiments is proposed to minimize the load disturbance integral error (IE) by maximizing the integral gain, subject to a desired phase ...
