Valve stiction is one of the main reasons which lead to control loop oscillation.However, there is not a mature method to diagnose the stiction.Under the premise of unknown the control system model,this paper put forward a new method based on the process output signal processing to realize control valve stiction of fault diagnosis.The results of the experiment and simulation to show that the method is effective.
