Most modern machineries and industrial processes are manipulated using advanced control technologies. With the recent advances in information technology, more and more control systems operate over communications networks. However, the technologies used in these control systems are seriously lagging behind because they make little assumptions about problems in digital communications. These problems include sampling errors, quantization errors, transmission errors and transmission delays. The proposed research will develop a new control theory to address this issue. Our work will help Australia maintain a leading role in the area of control and give the Australian industry advantages in applying modern technologies in control and automation.Read moreRead less

The study of wear debris using advanced technologies. A large portion of the operating cost of machinery is associated with wear due to the interaction between moving surfaces, which generates wear particles as by-products. The wear particles thus carry information regarding the wearing process, and can be used to assess the machine's condition and further facilitate failure prediction and minimise maintenance. This project will explore the mechanisms and possible influence of corrosion on the w ....The study of wear debris using advanced technologies.

The techniques to be developed in this project should become the international standard for diagnostic and prognostic techniques for high speed gearboxes, and improve the performance of Australian industry. Australia being a major supplier of natural resources, with many mines in remote locations, it is heavily dependent on machine condition monitoring techniques, such as those being developed in the project, to maximise output and minimise the likelihood of catastrophic failure. The techniques also give improved safety, for example of helicopters, which are suspended from the gearbox, making it a very critical component. This will be of considerable benefit to both civil and military operators of helicopters, both important to Australia.Read moreRead less
