Abstract
Relay feedback auto-tuning test is used for estimation of critical point i.e. ultimate gain and ultimate period for designing process control systems. An experimental technique is proposed for improved estimation of the critical point by conducting the relay feedback test for two different hysteresis bands. Simulation results show that the critical point estimation by our proposed method is superior to standard relay feedback method, and very close to the actual one. Usefulness of the proposed method is demonstrated through close-loop control performance for both set-point change and load disturbance.
