Abstract Stiction is a well known problem of the process performance. Compensate its effect is essential, because most of sticky valves cannot be replaced and they remain working for months or years. The scope of this work is to propose a novel methodology to compensate stiction effects, through the modification of the controller (PI) block in the control loop. The proposed approach is based on the two moves method, however it allows to specify closed loop performances faster than open loop and… Expand
Compensation of control valve stiction through controller tuning

In many industrial manufacturers, the quality of product heavily depends on control loop performance. Oscillations in control loop decreases performance of their systems. This is made worse with theExpand
Fuzzy I + PD controller for stiction compensation in pneumatic control valve
Stiction in control valves induces oscillations in process variables which consequently bring down product quality and efficiency, quickens wear and tear, and prompts unsteadiness in the plant. InExpand
Stiction in control valves is an extremely nonlinear and one of the long-standing problems in a closed loop control system, since the controller will push the control valve to move until theExpand

Controller structure for plants with combined saturation and stiction
This approach shows that, for systems affected by a certain class of nonlinearities and saturation at the actuator, the addition of a right inverse of the nonlinearity, in series with the plant, results in a saturation. Expand
