Verification of advanced controllers for safety-critical systems
In order to design and deploy a feedback controller in a real application, one must determine suitable specifications that the design must meet ("validate"), and then ensure that the chosen specifications have been met ("verify"). In this thesis, we investigate a verification paradigm based on …

Advanced controllers for building energy management systems. Advanced controllers based on traditional mathematical methods (MIMO P+I, state-space, adaptive solutions with constraints) and intelligent solutions (fuzzy logic and genetic algorithms) are investigated for humidifying, ventilating and air-conditioning applications.
… building energy management systems (BEMS). The controllers considered include the multi PI-loop controllers, state-space designs, constrained input and output MIMO adaptive controllers, fuzzy logic solutions and genetic algorithm techniques. The control performances of the designs developed …

Design of Robust PID Controllers with Constrained Control Signal Activity
… presents a new method for design of PI and PID controllers with the level of control signal activity taken into consideration. The main reason why the D-part is often disabled in industrial control loops is because it leads to control signal sensitivity of measurement noise. A frequently varying …

Modular modeling and control of a hybrid unmanned aerial vehicle’s powertrain
… of charge dynamics. The proposed models and controllers are experimentally validated on a novel hybrid electric UAV powertrain testbed. The controllers are evaluated on three core figures of merit: performance, reliability, and efficiency. Both simulation and experimental results show that …

Collaborative Simulation of Reacting Flow and Controller in Chemical Looping Systems
… become more complex and diverse, process controllers are increasingly required to optimise system performance and ensure stable operation. This is particularly true in energy-intensive industries, where multiphase reactive systems are highly dynamic and sensitive to fluctuating conditions. …

System identification and control of magnetic bearing systems
… here set out to design both conventional and advanced controllers based on the system model. This research report demonstrates that the literature on AMBs shows that AMBs are making their mark in the industry; they are increasingly being used in applications including jet engines, compressors, …

Transient stability assessment of hybrid distributed generation using computational intelligence approaches
… power electronic interface circuits, advanced controllers etc., the present power system network is now more complex than in the past. Consequently, the recent rate of blackouts recorded in some parts of the world indicates that the power system is stressed. The real time/online …
