Relay feedback is a method used in control systems to tune PID gains automatically. It involves applying a relay to the system, which generates oscillations that help identify the system's response characteristics. The goal is to adjust the proportional, integral, and derivative gains based on the feedback obtained from these oscillations. Initial research indicates that there are numerous resources available online, including informative papers on the subject. Understanding relay feedback is essential for effectively implementing it in PID control tuning.
