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.

Data obtained in-situ enable direct computation of solids assembly properties and their permeability to fluids. A specific application involving aggregate formation and sediment networks could be evaluated through micro-scale analysis combined with robust fluid flow simulations. The method can potentially be utilized to predict trends such as filtration behaviour of materials under different states of compression. This offers significant benefits in formulating the design of flocculated systems pertinent to a number of industrial sectors wishing to design optimum solid-liquid separation processes.Read moreRead less
New drives and control techniques for high performance piezoelectric actuation. Piezoelectric actuators are made from a ceramic material that expands in response to an applied voltage. Although these actuators develop the greatest forces and most precise motion of any actuator, a number of performance limitations exist. This proposal aims to overcome these limitations and greatly increase the performance of piezoelectric actuators.

Although these actuators develop the greatest forces and most precise motion of any actuator, a number of performance limitations exist. This proposal aims to overcome these limitations and greatly increase the performance of piezoelectric actuators.
Improved piezoelectric actuators will result in a parallel improvement of analytic and process machines throughout the scientific and industrial community.

Analysis, Optimization, and Control of Scanning Atomic Force Microscope Micro-Cantilever Probes. Atomic Force Microscopes (AFM's) are widely used for the examination of samples smaller than can be observed with an optical microscope. A tiny 'finger', only a few atoms wide at its sharpest point, is used to 'feel' the surface of a sample. This project aims to increase the resolution of AFM images by actively controlling the sensor probe dynamics.
