Jonker, Tim (author), Duinkerken, M.B. (author), Yorke-Smith, N. (author), de Waal, A. (author), Negenborn, R.R. (author)Increasing international maritime transport drives the need for efficient container terminals. The speed at which containers can be processed through a terminal is an important performance indicator. In particular, the productivity of the quay cranes (QCs) determines the performance of a container terminal; hence QC scheduling has received...journal article 2019

Li, S. (author), Liu, J. (author), Negenborn, R.R. (author)Over the past two decades, a number of methods have been proposed for solving maritime collision avoidance problems. Most of these works take a single ship's perspective and focus on one-to-one or one-to-many situations. To more complicated many-to-many situations, less attention has been paid. To deal with the many-to-many collision...journal article 2019

Haseltalab, A. (author), Negenborn, R.R. (author)Over the last few years, autonomous shipping has been under extensive investigation by the scientific community where the main focus has been on ship maneuvering control and not on the optimal use of energy sources. In this paper, the purpose is to bridge the gap between maneuvering control, energy management, and the control of the Power and...journal article 2019

Tian, X. (author), Guo, Y. (author), Negenborn, R.R. (author), Wei, Lingna (author), Lin, N.M. (author), Maestre, José María (author)Operational water resources management needs to adopt operational strategies to re-allocate water resources by manipulating hydraulic structures. Model Predictive Control (MPC) has been shown to be a promising technique in this context. However, we still need to advance MPC in the face of hydrological uncertainties. This study makes the first...journal article 2019

Haseltalab, A. (author), Negenborn, R.R. (author)Motion control is one of the most critical aspects in the design of autonomous ships. During maneuvering, the dynamics of propellers as well as the craft hydrodynamical specifications experience severe uncertainties. In this paper, an adaptive control approach is proposed to control the motion and trajectory tracking of an autonomous vessel...journal article 2019

Chen, L. (author), Hopman, J.J. (author), Negenborn, R.R. (author)Compared to an individual Autonomous Surface Vessel (ASV), greater efficiency and operational capability can be realized by a team of cooperative ASVs for certain operations, such as search and rescue, hydrographic survey and navigation assistance. This paper focuses on cooperative floating object transport, i.e., a group of ASVs coordinate...journal article 2019

Li, Shijie (author), Liu, Jialun (author), Negenborn, R.R. (author), Ma, Feng (author)Ship collision is the main type of maritime accidents, which causes great losses on human lives and economy, and brings negative impacts to the maritime environment. In crowded waters such as the sea area near a seaport, multiple ships encountering situations happen frequently. While several methods have been proposed for solving multiple...journal article 2019

Wang, L. (author), Wu, Qing (author), Liu, Jialun (author), Li, Shijie (author), Negenborn, R.R. (author)At present, with the development of waterborne transport vehicles, research on ship faces a new round of challenges in terms of intelligence and autonomy. The concept of maritime autonomous surface ships (MASS) has been put forward by the International Maritime Organization in 2017, in which MASS become the new focus of the waterborne...journal article 2019

Liu, Chenguang (author), Zheng, Huarong (author), Negenborn, R.R. (author), Chu, Xiumin (author), Xie, Shuo (author)Since vessel dynamics could vary during maneuvering because of load changes, speed changing, environmental disturbances, aging of mechanism, etc., the performance of model-based path following control may be degraded if the controller uses the same motion model all the time. This article proposes an adaptive path following control method...journal article 2019
