    • 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   Characterization of Limit Cycle Oscillations Induced by Fixed Threshold Samplers 

      Miguel-Escrig, Oscar; Romero Pérez, Julio Ariel; Sánchez-Moreno, José; Dormido, Sebastian IEEE (2022-06-13)
      In this work, a generalized study of the conditions for the appearance of limit cycle oscillations induced by any kind of sampler with multilevel fixed thresholds is presented. These kinds of samplers, which will be referred ...

    • 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 ...

    • openAccess   On-line retuning of PID controllers with fixed threshold samplers 

      Miguel-Escrig, Oscar; Romero Pérez, Julio Ariel; Sánchez-Moreno, José; Dormido, Sebastian Elsevier (2023-04-11)
      The appearance of limit cycle oscillations in control systems with fixed threshold based samplers degrades the performance of the control loop, accelerates the wear out of actuators, and introduces an unnecessary communication ...
