Disturbance rejection in 2 x 2 linear hyperbolic systems

OM Aamo - IEEE transactions on automatic control, 2012 - ieeexplore.ieee.org
Many interesting problems in the oil and gas industry face the challenge of responding to
disturbances from afar. Typically, the disturbance occurs at the inlet of a pipeline or the …

Review of two-phase flow models for control and estimation

UJF Aarsnes, T Flåtten, OM Aamo - Annual Reviews in Control, 2016 - Elsevier
Most model-based control and estimation techniques put limitations on the structure and
complexity of the models to which they are applied. This has motivated the development of …

Boundary observer design for hyperbolic PDE–ODE cascade systems

A Hasan, OM Aamo, M Krstic - Automatica, 2016 - Elsevier
