Unified Control for the Permanent Magnet Generator and Rectifier System
… Since the generator and the rectifier can be controlled simultaneously, it would be very desirable to develop a unified control. With this unified control, the boost inductors between the PMG and rectifier is eliminated, which significantly reduce the volume and the weight of the whole system …

Facilitating seamless transitions in flexible microgrids: A unified control systems framework for enabling multi-mode inverters
… typically employs highly specialized control algorithms and operation modes for the comprising DC/AC inverters, particularly in the primary control layer. This approach hinders the true potential of flexible microgrids to dynamically respond to changing generation and consumption …

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 …

Investigations into controllers for adaptive autonomous agents based on artificial neural networks.
… the initial aim was to design and implement a unified architecture integrating sensorimotor learning and overall control. This was intended to overcome shortcomings of typical behaviour-based approaches in reactive control settings. It was achieved in two stages. Initially, feedforward neural …

An Analysis and Improvement of Robo-Advisory
… in profiling and portfolios, the absence of a unified dynamic formalism, the lack of a scalable, auditable LLM-driven RA, and limited risk-matched evidence on realised outcomes. Six questions frame the work: RQ1–RQ2 on questionnaires, portfolios and strategies; RQ3 on a mathematical framework; …

Passivity, no-regret, and performance in online learning and games
… to achieve complex goals. This thesis develops a control- and game-theoretic foundation to analyze and ultimately synthesize such systems in which adaptive agents evolve in the presence of other adaptive agents. Building on this motivation, the thesis investigates the interplay between passivity, …
