Fault Diagnosis for Level Control System Based on IDEF

Abstract:

Article Preview

In order to improve the dynamic stability of level control system in the steam drum of boiler, a fault diagnosis approach is proposed by using IDEF method, which can analyze the control system structure by the IDEF model. When the faults occur, the possible causes of fault can quickly be identified by using the model. The approach can provide a reliable basis of decision-making for the control and make a reasonable fault diagnosis in a timely and accurate manner. Using the method can effectively improve the speed of fault diagnosis, prevent the fault occurs, ensure safety and stable operation for the boiler control system.
