Magnetic bearing systems have received much attention in the research community for the past decades. Its inherent nonlinearity and open-loop instability present challenges for controller design. This thesis investigates and designs model predictive control (MPC) systems for an experimental Active Magnetic Bearing (AMB) laboratory system. A host-target development environment of real-time control system with hardware in the loop (HIL) is used for implementation of the predictive control systems. In this thesis, both continuous and discrete time model predictive controllers are studied.

The study determines the predominant hydrogeological controls on salinity distribution and salinization/freshening, proposing conceptual models to explain the different vertical distributions of groundwater salinity at the coastline. An improved understanding of the sources of salinity and the hydrogeological controls will subsequently provide support for the future management of groundwater in the Western Port Basin, and serve as a template for how to unravel complex salinity distributions in coastal aquifers, and their relationships to palaeo- and recent geomorphological histories.

This thesis intends to develop application-level access control models to address several major security issues in enterprise environments. The first goal is to provide simple and efficient authorization specifications to reduce the complexity of security management. The second goal is to provide dynamic access control for Web service applications. The third goal is to provide an access control framework for Semantic Web services. In this thesis, an Authorization-Function-Based Role-based Access Control (FB-RBAC) model is proposed for controlling enterprise systems at the application level.

Model Predictive Control (MPC) refers to a class of algorithms that optimize the future behavior of the plant subject to operational constraints. The merits of the class algorithms include its ability to handle imposed hard constraints on the system and perform on-line optimization. This thesis investigates design and implementation of continuous time model predictive control using Laguerre polynomials and extends the design approaches proposed in to include intermittent predictive control, as well as to include the case of the nonlinear predictive control.

The main focus of this thesis is on the application of a model predictive control (MPC) method to devise an ABS for a BBW vehicle. Unlike the traditional ABS control algorithms which are based on a trial and error method, the MPC based ABS algorithm aims to utilizes the behaviour of the model to optimize the wheel slip dynamics subject to system constraints. Performance of the proposed wheel slip controller is validated through Software-in-the-Loop (SiL) and Hardware-inthe-Loop (HiL) simulation.

In this thesis, focus on the wireless links between devices equipped by deployed operating personnel and intermediary access point infrastructure. We use multi-radio (MR) platforms, wireless devices with multiple and diverse transceiver technologies, to produce robust and reliable links through adaptive control of available transceivers. Primarily, we study the application of intelligent control techniques, namely reinforcement learning (RL), for adaptive control over diverse transceivers to achieve the desired robustness and reliability under dynamic environmental conditions.

This thesis presents an evaluation of the mapping performance of a variety of SLAM algorithms that are freely available in the Robot Operating System (ROS), in conjunction with ranging data from various ranging sensors suitable for use onboard small UAS. To compare the quality of the generated maps, an existing metric was initially employed, however deficiencies noted in this metric led to the development of two new metrics. A discussion of both the existing and new map quality metrics, and the advantages and disadvantages of each, is presented as part of this thesis.

The present study draws from two major bodies of literature: (1) research on leadership, which recognizes the important role of leaders in driving organizational performance and that leadership style may differ across individuals; and (2) the MCS literature, including RM concepts, in which control systems are viewed as mechanisms to “assist the organization in managing its risk and to promote effective governance processes” (Krogstad et al., 1999, p.

The primary aim of this research was to further develop the sensing and estimation module of the CHMS framework with an improved multimodal inference model of MWL as needed for the application in aerospace CPHS. Here the focus of this research was on the implementation of a multimodal inference model of MWL that would be developed and experimentally tested. This was done with the purpose of studying the viability of real‐time system adaptation in aerospace systems.

The purpose of this research is to model the factors affecting a production and inventory system that combines returns and remanufacturing, and to evaluate effective control strategies in order to improve the performance of the system. In this regard, the main steps adopted to conduct the modelling process initially involved an investigation of reverse logistics and closed loop supply modelling as reported in the literature. An investigation of previous models developed contributed to our research by increasing the knowledge required to conduct the modelling.

This thesis focuses on the management control function in Australian small businesses. The main function of a Management Control System (MCS) is strategy implementation. It is the system used by management to plan and control the firm’s performance. Elements of the MCS include strategic planning, budgeting, resource allocation, forecasting, performance measurement and evaluation and the core management accounting system (Anthony & Govindarajan, 2007).
