• A hybrid kinematic controller for resilient obstacle avoidance of autonomous ships 

      Marley, Mathias; Skjetne, Roger; Breivik, Morten; Fleischer, Caroline (Peer reviewed; Journal article, 2020)
      Resilience is an important feature of autonomous systems. To be resilient, a control system must be stable, robust, and safe. This paper explores the use of hybrid feedback controllers to ensure robustness towards uncertainties ...
    • Maneuvering with safety guarantees using control barrier functions 

      Marley, Mathias; Skjetne, Roger; Basso, Erlend Andreas; Teel, Andrew R. (Journal article; Peer reviewed, 2021)
      Control barrier functions (CBFs) ensure safety of controlled dynamical systems, by restricting the control inputs to render desired sets forward invariant. In this paper we propose a dynamic guidance scheme for autonomous ...
