    • Relay Feedback Identification with Shifting Filter for PID Control 

      Autor: Hofreiter M.
      (IFAC, 2020)
      The paper describes a recently introduced relay shifting method for process identification using a single relay feedback test. The aim is to obtain a process model for automatic tuning of PID controllers. This method is ...
    • Relay Identification Using Shifting Method for PID Controller Tuning 

      Autor: Hofreiter M.
      (Multidisciplinary Digital Publishing Institute (MDPI AG), 2021)
      The aim of this study was to present a relay shifting method for relay feedback identification of dynamical systems suitable for PID controller tuning. The proposed technique uses a biased relay to determine frequency ...
