Peak Shaving the Electrical Power Demand of Ship-to-shore Cranes: Developing operational policies to maintain productivity under increasingly restrictive peak power limitations

Electrification of numerous end-users is a worldwide trend to address climate change, according to the International Energy Agency. This trend has also reached container terminal operators. Currently most of the ship-to-shore cranes employed are electrified, leading to an increase in the required electrical power demand and to an increase in the...

Data-based modal space control for active damping

This research presents a novel data-based modal control method for actively dampening the flexible mode in a multi-input multi-output (MIMO) system. Traditional passive damping methods add significant mass to the system, making recent advances in sensor and actuator technology, such as lightweight piezoelectric materials, a more appealing...

Metastructures in a sensor-actuator configuration: the practical issues in bandgap generation

Undesired vibrations are one of the most significant sources of error in any type of mechatronic system or component. The emerging field of elastic (locally resonant) metamaterials offers a viable solution to successfully suppress these by generating bandgaps in both resonant and non-resonant regions. In this thesis, metamaterials in a sensor...

Model-based Integrated Planning and Control of Autonomous Vehicles using Artificial Potential Fields

Navigation systems in an Autonomous Vehicles (AV) can be divided into two parts: a path planning block which takes in the environmental data and rules to design a collision-free obstacle and a vehicle control and tracking block which generates actuator inputs for the AV to follow the reference path generated by the path planning block. Each task...

Modelling the influence of large-scale profit optimising energy storage systems participating in both energy and balancing markets

As the share of renewable energy generation increases, the need for energy storage also increases. Therefore, there is a need for better storage representation in the current energy modelling tools. In the present day,<br/>the longer-term energy storage systems are not fully represented since, for existing storage systems, the self-serving...
