Exhaust Gas Recirculation Control for Large Diesel Engines - Achievable Performance with SISO Design
Hansen, Jakob Mahler; Blanke, Mogens; Niemann, Hans Henrik; Vejlgaard-Laursen, Morten (Journal article; Peer reviewed, 2013)This paper investigates control possibilities for Exhaust Gas Recirculation (EGR) on large diesel engines. The goal is to reduce the amount of $NO_x$ in the exhaust gas by reducing the oxygen concentration available for ... -
Nonlinear observer design for GNSS-aided inertial navigation systems with time-delayed GNSS measurements
Hansen, Jakob Mahler; Fossen, Thor I.; Johansen, Tor Arne (Journal article; Peer reviewed, 2017)Global navigation satellite system (GNSS) receivers suffer from an internal time-delay of up to several hundred milliseconds leading to a degeneration of position accuracy in high-dynamic systems. With the increasing ... -
Nonlinear Observer for Tightly Coupled Integrated Inertial Navigation Aided by RTK-GNSS Measurements
Hansen, Jakob Mahler; Johansen, Tor Arne; Sokolova, Nadezda; Fossen, Thor I. (Journal article; Peer reviewed, 2018)A modular nonlinear observer is considered for tightly coupled integration of inertial measurements with global satellite measurements. A real-time-kinematic (RTK) approach is utilized where the rover and base station ... -
Nonlinear Observer for Tightly Integrated Inertial Navigation Aided by Pseudo-Range Measurements
Johansen, Tor Arne; Hansen, Jakob Mahler; Fossen, Thor I. (Journal article; Peer reviewed, 2017)A modular nonlinear observer for inertial navigation aided by pseudo-range measurements is designed and analyzed. The attitude observer is based on a recent nonlinear complementary filter that uses magnetometer and ... -
Nonlinear Observers for Inertial Systems aided by Real-Time Kinematic Global Navigation Satellite Systems
Hansen, Jakob Mahler (Doctoral theses at NTNU;2017:61, Doctoral thesis, 2017)This thesis is motivated by recent interest in nonlinear observers for navigation. The field of navigation is dominated by the Kalman filter and its variants. However, nonlinear observers offer some advantages, compared ... -
Nonlinear Observers for Integrated INS/GNSS Navigation – Implementation Aspects
Bryne, Torleiv Håland; Hansen, Jakob Mahler; Rogne, Robert Harald; Sokolova, Nadezda; Johansen, Tor Arne; Fossen, Thor I. (Journal article, 2017)Navigation is a term with broad usage in everyday life and can mean the act of moving, moving through an unknown environment, ascertaining a craft's position, or even browsing on the Internet. Originally, the term meant ... -
Robust Navigation of UAV using Inertial Sensors Aided by UWB and RTK GPS
Gryte, Kristoffer; Hansen, Jakob Mahler; Johansen, Tor Arne; Fossen, Thor I. (Chapter; Conference object, 2017)Tight integration of ultra wideband (UWB) range measurements with real-time kinematic (RTK) aiding of inertial navigation for increased robustness to GNSS dropouts, is achieved using a double-differenced nonlinear observer. ...
