Abstract
A procedure that compensates for static friction (suction) in control valves is presented. The compensation is obtained by adding a pulse sequence to the control signal. The characteristics of the pulse sequence are determined from the control action. Industrial field tests show that the procedure reduces the control error during stick-slip motion significantly compared to standard control without stiction compensation.
