Control Valve Stiction Compensation - Part II: Performance Analysis of Different Stiction Compensation Methods
Control valves are important elements of control loops. Stiction in control valves limits the performance of control loops. It decreases the life of control valves. Minimizing the negative impact of sticky control valves can improve the performance of control loops. This is the second part of a two-part study on control valve stiction compensation. In the first part, a novel stiction compensation method has been proposed. This second part compares the performance of the proposed stiction compensator described in Part I with six other important stiction compensators that have appeared in the literature. The proposed compensator performs better than any of the other six compensators.
