Experimental Low-speed Positioning System with VecTwin Rudder for Automatic Docking (Berthing)
Dimas M. Rachman, Yusuke Aoki, Yoshiki Miyauchi +2
A VecTwin rudder system comprises twin fishtail rudders with reaction fins to increase its performance. With a constant propeller revolution number, the vessel can execute special…
Warm-started Semionline Trajectory Planner for Ship's Automatic Docking (Berthing)
Dimas M. Rachman, Atsuo Maki, Yoshiki Miyauchi +1
In the usual framework of control, a reference trajectory is needed as the set point for a feedback controller. This reference trajectory can be generated by solving a trajectory o…
Application of Linear Filter and Moment Equation for Parametric Rolling in Irregular Longitudinal Waves
Yuuki Maruyama, Atsuo Maki, Leo Dostal +1
Parametric rolling is one of the dangerous dynamic phenomena. In order to discuss the safety of a vessel when a dangerous phenomenon occurs, it is important to estimate the probabi…
System Parameter Exploration of Ship Maneuvering Model for Automatic Docking / Berthing using CMA-ES
Yoshiki Miyauchi, Atsuo Maki, Naoya Umeda +2
Accurate maneuvering estimation is essential to establish autonomous berthing control. The system-based mathematical model is widely used to estimate the ship's maneuver. Commonly,…
Optimization on Planning of Trajectory and Control of Autonomous Berthing and Unberthing for the Realistic Port Geometry
Yoshiki Miyauchi, Ryohei Sawada, Youhei Akimoto +2
To realize autonomous shipping, autonomous berthing and unberthing are some of the technical challenges. In the past, numerous research have been done on the optimization of trajec…
Distance between configurations in MCMC simulations and the geometrical optimization of the tempering algorithms
Masafumi Fukuma, Nobuyuki Matsumoto, Naoya Umeda
For a given Markov chain Monte Carlo (MCMC) algorithm, we define the distance between configurations that quantifies the difficulty of transitions. This distance enables us to inve…
