Oscillation Compensator using a new Controller PI-Fuzzy Control for Pneumatic Stiction Valve
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2017, Vol 12, Issue 2
Abstract
Static Friction is a very general reason for oscillations in control valves in the process industry. Most of the oscillation problem due to the nonlinearities as the stiction problem producing the limit cycle leading the increase of variability in the process. Stiction problem emerging in pneumatic valve due to the ages leads the oscillation steady state response. In this work, a review and evaluation of an existing improved method for Stiction compensation is undertaken. The existing method reduces variation in process variable and valve stem movement. Then a new method is developed to cater for the limitations observed during review and evaluation. This method uses PI-Fuzzy applied to remove presence of oscillation during close-open valve process. The PI Fuzzy control is a nonlinear control method which eliminates the Sticky valve. The performance of the new approach is compared to that of the improved stiction compensation. The superiority in performance of the proposed PI fuzzy controller compensators is demonstrated through simulation in Simulink/MATLAB.
