On-line Detection of the Change of Friction in Control Valve
The function of stuffing box in pneumatic control valve is dynamic seal, but it also produces friction. The friction will affect the performance of position control. This paper proposes a method, based on the error integral indexes of control loop. On-line detection of the change of friction in cont...
