Abstract: Frequency adaptation in application to managed pressure drilling control is studied. It is noted that the main problem is to maintain constant annulus pressure in a presence of external disturbances and system parameters drift while the well depth changes. To solve it the frequency adaptation is used and an adaptive annulus pressure control system is build. Given are the results of numerical simulation and experimental investigations on a plant implementing the managed pressure drilling technology.

Keywords: frequency adaptation, linearization, PID-control, drilling, MPD technology.
