APPARATUS AND METHOD FOR STICTION COMPENSATION IN A PROCESS CONTROL SYSTEM |
摘要 |
An apparatus, method, and computer program for stiction compensation in a process control system (100) are provided. A determination is made as to whether a valve (102) is suffering from stiction. A control signal (116) provided to the valve (102) is adjusted in order to at least partially compensate for the stiction suffered by the valve (102) . Adjusting the control signal (116) could include (i) adjusting the control signal (116) to cause the valve (102) to move into a steady-state position and (ii) adjusting the control signal (116) to cause the valve (102) to remain in the steady-state position. Adjusting the control signal (116) to cause the valve (102) to move into the steady-state position could include (a) adjusting the control signal (116) to cause the valve (102) to move from a current position into a new position and (b) adjusting the control signal (116) to cause the valve (102) to move from the new position into the steady-state position. |
