Backlash estimation for industrial flexible drive-train systems
Papageorgiou, Dimitrios; Blanke, Mogens; Niemann, Hans Henrik; Richter, Jan H. (Journal article; Peer reviewed, 2017)Backlash in gearing and other transmission components is a common positioning-degrading phenomenon that develops over time in industrial machines. High-performance machine tool controls use backlash compensation algorithms ... -
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 ... -
Modelling and identification for control of gas bearings
Theisen, Lukas R. S.; Niemann, Hans Henrik; Santos, Illmar F.; Galeazzi, Roberto; Blanke, Mogens (Journal article; Peer reviewed, 2015)Gas bearings are popular for their high speed capabilities, low friction and clean operation, but suffer from poor damping, which poses challenges for safe operation in presence of disturbances Feedback control can achieve ... -
Stability Boundaries for Offshore Wind Park Distributed Voltage Control
Gryning, Mikkel P. S.; Wu, Qiuwei; Kocewiak, Lukaz; Niemann, Hans Henrik; Andersen, Karsten H.P.; Blanke, Mogens (Journal article; Peer reviewed, 2016)In order to identify mechanisms causing slow reactive power oscillations observed in an existing offshore wind power plant, and be able to avoid similar events in the future, voltage control is studied in this paper for a ...
