The shipping industry is facing increasing demands to reduce its environmental footprints. This has resulted in adoption of new and more environmental friendly power sources and fuels for on-board power generation. One of these novel power sources is the Solid Oxide Fuel Cell ...
Ship hybridization has received some interests recently in order to achieve the emission target by 2050. However, designing and optimizing a hybrid propulsion system is a complicated problem. Sizing components and optimizing energy management control are coupled with each othe ...
The maneuvering control of autonomous vessels has been under extensive investigations by academic and industrial communities since it is one of the primary steps towards enabling unmanned shipping. In this paper, a model predictive control (MPC) approach is presented for traje ...
The collaborative autonomous shipping experiment (Case)
Motivations, theory, infrastructure, and experimental challenges
The future autonomous ships will be operating in an environment where different autonomous and non-autonomous vessels with different characteristics exist. These vessels are owned by different parties and each uses its owned unique approaches for guidance and navigation. The C ...

Fuel-efficient vessel train formations for all-electric autonomous ships
In this paper, a distributed control approach is proposed to enable fuel-efficient Vessel Train Formations (VTF) in inland waterways and port areas for addressing the efficiency and environmental issues of transport over water. For path tracking, collision avoidance, and conse ...
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 maneu ...
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 c ...
Control for autonomous all-electric ships
Integrating maneuvering, energy management, and power generation control
In this paper, a predictive power management algorithm is proposed for all-electric ships with DC power distribution architecture with which it is insured that the provided power by each set of the Diesel-Generator-Rectifier (DGR) settles around the optimal point on Specific F ...
Adaptive control for a class of partially unknown non-affine systems
Applied to autonomous surface vessels
In this paper, a neural network-based adaptive control algorithm is proposed for a class of non-affine systems where the nonlinear influence of the system input on the states is unknown. The algorithm transforms the problem of controlling non-affine systems to control of nonli ...
In this paper, the convergence rate and time analysis of a fault-tolerant consensus algorithm that we proposed in [1] is carried out for asynchronous and synchronous partially connected networks with delay on communication paths. The results are also extended to the case of ne ...
