Adaptive Redesign of Nonlinear Observers with
Application to an Oil Well Drilling System

Abstract:
A new adaptive observer (re)design is developed for nonlinear systems that have uncertain terms with
regressors containing nonlinearities in unmeasured states. The design was originally motivated by the
pressure estimation problem in an oil well drilling system, and this case will be presented along with a
couple of other examples. The general design relies on the solution of a partial differential equations,
however, in many cases the PDE reduces to an ordinary differential equation for which a solution
can be found in closed form.
About the Speaker:
Ole Morten Aamo received his MSc and PhD degrees in Engineering Cybernetics from the Norwegian
University of Science and Technology (NTNU) in 1992 and 2002, respectively, and is currently a
