RESUMO
A non linear mathematical model (gas-liquid-solid), representing an oil well drilling system, was developed, based on mass and momentum balances, in order to implement classic control (PI), using mud pump flow rate as manipulated variable for controlling annulus bottom-hole pressure. An experimental unit was built in order to represent the control problems commonly observed in oil well drilling: tracking of the annulus bottom-hole pressure set point for respecting operational windows and rejection of density perturbation. Experimental PI controller tuning was performed based on Ziegler-Nichols (open loop), Cohen-Coon and Ziegler-Nichols (closed loop) tuning schemes.
