Control of an Underwater Robot System Connected to a Ship by a Slender Marine Structure
Li, Wei (Master thesis, 2008)This report addresses the stabilization problem of a marine structure (i.e. cable/riser), connected to a surface vessel at one end and to a thruster unit at the other. Here, only motion in the lateral direction has been ... -
Detection of Stiction in Control Valves: an Algorithm for the Offshore Oil and Gas Industry
Kvam, Asgeir (Master thesis, 2009)Valve stiction is one of the largest stand-alone reasons for oscillatory behavior in process industry. It is reported by Siemens Oil and Gas that valve stiction is a problem that is hard and time consuming to detect at ... -
Observer Design for Mechanical Systems described by Semilinear Partial Differential Equations
Nguyen, Tu Duc (Doktoravhandlinger ved NTNU, 1503-8181; 2004:86, Doctoral thesis, 2004)This doctoral thesis presents new analysis tool for observer design of flexible mechanical systems described by partial differential equations (PDEs). This work focuses especially on designing of natural observers. ...
