Naval ship control systems.
… view of the state of the art in Naval Ship Control Systems. This study covers material that is concerned with conventional Naval Surface Ships such as Destroyers and Frigates. Fire Control Systems are not considered because such studies already exist at the present time.

Piecewise Linear Control Systems
… treats analysis and design of piecewise linear control systems. Piecewise linear systems capture many of the most common nonlinearities in engineering systems, and they can also be used for approximation of other nonlinear systems. Several aspects of linear systems with quadratic constraints are …

Variable structure control systems
… and to apply the developed design concepts to control practical systems. It introduces the concept of a structure. The main aim in designing variable structure controllers, is to synthesize a variable structure system from two or more single structure systems, in such a way that the ensuing …

Management Control Systems and Sustainability
… These organisations utilise their management control systems (MCS) to organise their operations and thereby moving humanity further away from achieving this state. Extant research at the intersection of sustainability and current MCS primarily focuses on this incompatibility. As a result to …

Performance assessment of multivariate control systems
… hundreds to thousands of loops under automatic controls. Poorly performing control loops cause off-spec product, waste energy, and cause maintenance and safety issues. Much of the process control engineer's time is spent finding the root cause of poor performance, meanwhile many underperforming …

Strategies for wireless networked control systems
Networked Control Systems (NCS) and Wireless Networked Control Systems (WNCS) are control systems where controllers, sensors and final elements of control are connected to a mutual communication network. The inclusion of the network introduces delays and dropouts, which greatly influence the …

Intrusion detection for industrial control systems
<p>Industrial Control Systems (ICS) are rapidly shifting from closed local networks, to remotely accessible networks. This shift has created a need for strong cybersecurity anomaly and intrusion detection for these systems; however, due to the complexity and diversity of ICSs, well defined and …

Transmission of Information in Control Systems
For decentralized control, we study multisensor and multicontroller architectures. For such decentralized structures, we introduce lower bounds on information rates leading to the existence of controllers and coders leading to stability. We further obtain stabilizing decentralized coder and …

The sustainability of motion control systems
… in the past few decades, the demand for motion control systems in structures has skyrocketed. Many different technologies for combating wind and earthquake loads have been identified. Energy dissipation devices and base isolation are two methods that reduce the damage and minimize the response …

Security of Communication-Based Train Control Systems
Communication-Based Train Control (CBTC) systems are automatic train control systems that rely on bidirectional communications between trains and wayside units to exchange train status information and operational commands. Introducing wireless technologies changed train control systems to …

Dynamically reconfigurable hardware for embedded control systems
… hardware for the realisation of embedded control systems, using the most well-known example of this kind of technology: Field Programmable Gate array (FPGA). The focus of the first part of the thesis is on assessing the resource utilisation of FPGA- and CPU-based realisations, relating the …

Privacy-Aware Risk-Based Access Control Systems
… In order to unlock this potential, while controlling the privacy risk, it is necessary to develop novel data sharing and access control mechanisms able to support risk-based decision making and weigh the advantages of information against privacy considerations. To achieve this, access …

Flexible Embedded Control Systems : Design and Implementation
Embedded control system design is a complex and error prone task, and there is a great need for better development tools. Today most real-time control systems are static systems, designed in an ad-hoc fashion. A more interactive way of working would give shorter development times, reduced costs for …
