Design and Comparison of Constrained MPC with PID Controller for Heave Disturbance Attenuation in Offshore Managed Pressure Drilling Systems
Nikoofard, Amirhossein; Johansen, Tor Arne; Mahdianfar, Hessam; Pavlov, A (Journal article, 2014)This paper presents a constrained finite horizon model predictive control (MPC) scheme for regulation of the annular pressure in a well during managed pressure drilling from a floating vessel subject to heave motion. In ... -
Pressure Control for Offshore Managed Pressure Drilling (MPD): Analysis, Design, and Experimental Validation
Mahdianfar, Hessam (Doctoral thesis at NTNU;2016:96, Doctoral thesis, 2016)Deepwater offshore drilling operations are among the most complex activities. For example in regions such as the Gulf of Mexico, wells are drilled in water depths of up to 3 kilometers, drilling depths can exceed 6 ...
