Adaptive Autopilots for Large Tankers
- 1978
-
In: 7th Triennial World Congress of the IFAC : A Link Between Science and Applications of Automatic Control, Helsinki, Finland, 12-16 June - A Link Between Science and Applications of Automatic Control, Helsinki, Finland, 12-16 June. - 1474-6670. ; 11:1, s. 477-484
-
Conference paper (peer-reviewed)abstract
- The adaptive autopilots are based on velocity scheduling, a self-tuning regulator for steady state course keeping, a high gain turning regulator with variable structure, and a Kalman filter. Results from simulations and full-scale experiments on three different tankers are presented. The autopilots are shown to work excellently under different loads, speed and weather conditions.
