Robust Control and System Identification of Highly Resonant Systems. The modelling and control of complex and highly resonant systems is of increasing engineering importance due to their occurence in a wide variety of emerging areas in aerospace, acoustics, robotics and ``smart'' structures.

The modelling and control of complex and highly resonant systems is of increasing engineering importance due to their occurence in a wide variety of emerging areas in aerospace, acoustics, robotics and ``smart'' structures. At the same time, effective tools tailored towards identifying the necessary models, and synthesising the necessary controllers for these systems are in their infancy. This arises from special difficulties encountered via the high dimensionality of the structures involved. This research project will employ new methods from the fields of robust control and multivariable system identification theory to lead to new and high performance solutions in this area.Read moreRead less

Nanotechnology is the science of understanding and control of matter at dimensions of 100 nanometers or less. Encompassing nanoscale science, engineering, and technology, nanotechnology involves imaging, measuring, modeling, and manipulation of matter at this level of precision. An important aspect of research in nanotechnology involves precision control and manipulation of devices and materials at a nanoscale, i.e. nanopositioning. The primary goal of this proposal is the establishment of an experimental nanopositioning research facility to enable the development of a new generation of nanopositioners.

The proposed project promotes a conceptual advance in the application of plate waves for the quantitative reconstruction of laminar defects by investigating fundamental experimental and analytical aspects of a novel approach in plate wave ultrasonic tomography. A successful development will have a comparable significance in the area of health monitoring of thin structures as computer tomography had in medical imaging. Previous attempts have ignored wave scattering effects, and therefore do not describe the correct physics of the problem. With its combined experimental-numerical approach, the proposed fundamental studies will help to identify the potential of plate wave ultrasonic tomography for in-situ health monitoring of realistic structures and smart materials design.Read moreRead less

Structural integrity monitoring, to anticipate and prevent failure, is a multi-billion dollar effort worldwide. Detailed assessment of the capability of fibre Bragg gratings to measure strain profiles along the grating length, i.e. intragrating sensing, and thereby detect structural ?hot spots? before failure is essential for effective systems. They will be used to determine strain gradients similar to those found in common problem areas, such as the tips of elliptic notches and disbonding at the ends of composite joints. Additionally, grating refractive index profiles will be characterised using imaging techniques, to assess performance and possible changes to gratings after prolonged use.Read moreRead less
