Nils Christian A. Wilhelmsen received the M.Sc. degree in Engineering Cybernetics from NTNU in Trondheim, Norway in 2018 and the Ph.D. degree in Mathematics and Control from MINES ParisTech in 2021.

The general objective of his work is to develop a simplified mathematical model to describe the rolling motion of damping subs in the wellbore together with their slipping and to derive a method for detecting when the damping subs slip using IMU signals. This algorithm can be used together with active control algorithms for the damping subs which require knowledge of whether the damping sub is slipping or not. The research will use tools from mathematical modeling, control theory, and computer simulations.
