Design of Intelligent Electrical Valve Positioner with Fault Diagnosis Function
This paper describes the control characteristics of pneumatic regulating valves in intelligent electrical valve positioners and their fault diagnosis functions.The developed intelligent electrical valve positioner not only has fault self diagnosis function,but also has valve fault diagnosis and warning function by adding micro low power pressure sensors,self diagnostic circuits,and multi variable fusion algorithms.
