About

Research topics:

My research concerns control system functionality for autonomous ships. In autonomous ship operations, the control system needs to take over tasks that are traditionally performed by the operator, which introduces additional dynamics in the control loop. Research topics include:

• Formal methods for analyzing dynamics in the mission and guidance layer

• Sea state estimation

• Hybrid control of marine vessels

• Mathematical modeling of marine vessels

Teaching:

TMR4275 Modelling, Simulation and Analysis of Mechatronic Systems

TMR16 Hybrid Systems Theory for Marine Applications (3.75 credits, module)

PhD candidates:

(2020-) Fan Gao Hybrid combinator curves for autonomous ships

(2020-) Raphael Mounet Sea state estimation using a network of heterogenous wave sensors (Main supervisor: Ulrik D. Nielsen, DTU)

(2020-) Marco Nataletti Hydrodynamic performance of ship propulsion and resistance in a seaway ( Main supervisor: David Kristiansen)

(2021-) Susanna Dybwad Kristensen Risk modeling for autonomous vessels (Main supervisor: Ingrid B. Utne)
