• openAccess   Asymmetric delayed relay feedback identification based on the n-shifting approach 

      Sánchez-Moreno, José; Dormido, Sebastian; Miguel-Escrig, Oscar; Romero Pérez, Julio Ariel Taylor and Francis (2021-08-20)
      The paper presents an improvement of the n-shifting technique to identify the frequency response of an industrial process using a fully asymmetric and delaying relay. The n-shifting approach allows the calculation of n + 1 ...
    • 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 ...
    • openAccess   Multiple frequency response points identification through single asymmetric relay feedback experiment 

      Miguel-Escrig, Oscar; Romero Pérez, Julio Ariel; Sánchez-Moreno, José; Dormido, Sebastian Elsevier (2023-01)
      In this paper a methodology to identify several points of the frequency response of a system using a single experiment is proposed. The identification is performed using the information obtained from an asymmetric relay ...
