The Use of a Factory Simulation to Evaluate a Flexible Control Structure for Integrated Manufacturing
<p>Once a control structure for an integrated manufacturing system is decided upon, manufacturing activities are limited by that structure. A flexible control structure is presented as an approach for accommodating a variety of manufacturing activities, without being limited to a single control …

Improved renewable energy power system using a generalized control structure for two-stage power converters
The dissertation presents a generalized control structure for two-stage power converters operated in a renewable energy power system for smart grid and micro grid systems. The generalized control structure is based on the two-loop average-mode-control technique, and created by reconstructing the …

An evaluation of the implementation of ERM in the internal control structure of a fertilizer manufacturing organisation
… in respect of risk management and internal controls. This situation has worsened since the COVID-19 pandemic. The chemical manufacturing industry is no different to this phenomenon since organisations are struggling to identify and manage risk optimally due to ineffective risk management …

Dynamic Control Structures for Cooperating Processes (Elections, Deadlock Detection, Decentralized, Agreement)
… we consider the problem of how to select a control structure for a set of processes cooperatively providing a service. The control structure dictates how the processes cooperate in providing the service, and therefore determines the performance they achieve in carrying out the service. …

Plantwide Control System Design for IGCC Power Plants with CO2 Capture
… this paper, a systematic approach to design the control system of a commercial-scale integrated gasification combined cycle (IGCC) power plant with CO2 capture is considered. The control system design is developed with the objective of optimizing a desired scalar function while satisfying …

STAMP applied to Fukushima Daiichi nuclear disaster and the safety of nuclear power plants in Japan
… safety in Japan, what the potentially hazardous control actions could be. Because of the complex sociotechnical nature of nuclear power plants, System-Theoretic Accident Model and Processes (STAMP)-specifically, Causal Analysis based on STAMP (CAST) and System-Theoretic Process Analysis (STPA)-is …
