• 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   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 ...
