AI-baserat kontrollsystem för bärplansbåtar

Forskningsprojekt, 2024

 Foiling is a radical method for reducing the resistance of highspeed vessels. The foiling ferries were popular already in 70’s, however, due to the durability of the structure, high maintenance costs, and safety issues the technology development for the commercial craft was paused for a few decades. Thanks to more advanced materials such as composites, digitalization, and modern control systems, foiling is emerging once again as one of the solutions to reduce the environmental emissions from sea transport. Foiling becomes even more interesting in combination with the goals for the electrification of sea transport in Sweden as well as internationally. The drastic reduction of water resistance through foiling means that we can increase the range of electric ferries or decrease the required battery sizes for these vessels. Beside all the benefits, there are still challenges that must be resolved to make the technology ready for public use in realistic conditions such as different sea states. This means that a robust control system must be developed to make sure that the dynamic lift force on the hydrofoils, which for instance are caused by the waves, are filtered so that the passengers experience a smooth ride onboard. Such a control system can also increase the safety of the ride not only through a smooth rise but also by ensuring a safe landing on water in emergency conditions. The objective of this project is to develop an AI-based control system for a hydrofoil through a collaboration between the Division of Marine Technology and the Division of Vehicle Engineering and Autonomous Systems at M2. The intended users are the commercial and private hydrofoiling craft owners and operators.
