After cars and trains, research is also increasingly targeting autonomous shipping. Particularly problematic are manoeuvres in confined waters. These include mooring and unmooring, as well as manoeuvres to avoid collisions in harbours. These scenarios have been researched by the Chair of Automatic Controlled by Professor Thomas Meurer at Kiel University (CAU), and potential solution approaches investigated based on a mathematical model for ship dynamics. Using these approaches, autonomous manoeuvres could be implemented particularly efficiently, or the most economical solution determined through lower energy consumption. Professor Meurer’s team will present their concepts for autonomous shipping at the Hannover Messe, in an English presentation on Wednesday 3 April at 12pm and 2pm. "Automatic control principles and concepts can be found in almost all technical systems. They ensure the desired functionality of the system, taking various conditions into account. Examples include stabilisation systems in motor vehicles, robots, production plants or energy networks," explained Meurer. "The focus of our research is the modelling, optimisation, regulation and control of complex dynamic systems. For this purpose, we develop innovative approaches on the basis of mathematical models. We also implement our developments in technological and industrial fields of application. Aspects of cooperation and networking are increasingly important." Solution approaches for optimal timing, energy use and consumption in ship management Meurer is convinced that so-called predictive control is the key to solving the issue: "We assume that a mathematical description of the ship dynamics is required. The behaviour of the ship can be predicted, based on this description, which of course must mirror the real behaviour of a ship as closely as possible. With this information, a control system could specifically influence the current state of the vessel." For this purpose, the researchers particularly look at the position, orientation and speed of a ship, and the interaction with the ship’s propulsion and rudder over a specific time horizon. In addition, static as well as dynamically moving obstacles, such as other ships in the area, are explicitly taken into account. External disturbances like wind and currents are also incorporated into the calculations. In order to be able to react to changes in the parameters in real time, the Kiel researchers have evaluated and compared different approaches to optimal timing, energy use and consumption in ship management, as well as approaches to collision avoidance, because increased automation in shipping offers financial, energy-saving and environmental benefits and potential improvements. At the same time, safety increases, since assistance systems relieve the crew and reduce the risk of human error. As a next step, the working group will test their research on a laboratory scale, in order to more closely approximate controlling an automated vessel in confined waters. The Automatic Control Working Group at the Hannover Messe The Automatic Control Working Group’s (AG Regelungstechnik) methods for predictive control and real-time optimisation of autonomous ship management with automated collision avoidance will be presented from Monday 1 April to Thursday 4 April in virtual and interactive formats. On Wednesday 3 April at 12pm and 2pm, Professor Thomas Meurer will present "Automatic Control in (Inter)Action" on the CAU's stage. About the person: Prof. Meurer, born in Gaildorf, Baden-Württemberg, has been the head of the Chair of Automatic Control at the CAU’s Faculty of Engineering since November 2012. After studying at the University of Stuttgart (Dipl.-Ing., 2001) and Georgia Tech, Atlanta, USA (M.Sc., 2000), he completed his doctorate at the University of Stuttgart in 2005. From 2005 to 2007, he conducted post-doctoral research at Saarland University. In 2007, he became a Senior Researcher at the TU Wien (TUW), where he completed his post-doctoral lecture qualification in 2012. His research interests include control processes for complex dynamic systems and their technical application. He is an IEEE Senior Member, and Associate Editor of numerous journals. He chairs the Technical Committee 1.40 of the VDI/GMA. Prof. Meurer was awarded the VDI/GMA Eugen Hartmann Prize in 2009 and the Cardinal Innitzer Award in 2012, and in 2017 he received the IFAC Congress Best Interactive Paper Prize with two co-authors.
