Control Strategies for Idle Speed of Automotive Engines. Reduction of engine idle speed will provide significant improvements in fuel efficiency. Current techniques are based on simplified models of a complex engine system and as a result do not fully exploit the possible controller capability. Therefore this project proposes new engine models and will provide novel controller methods to address this problem. This should contribute to increased engine stability and faster torque response to dist ....Control Strategies for Idle Speed of Automotive Engines. Reduction of engine idle speed will provide significant improvements in fuel efficiency. Current techniques are based on simplified models of a complex engine system and as a result do not fully exploit the possible controller capability. Therefore this project proposes new engine models and will provide novel controller methods to address this problem. This should contribute to increased engine stability and faster torque response to disturbances like air conditioner engagement, for both LPG and gasoline injected engines, thus allowing the engine idle speed to be lowered without risking stall or impairing the engine Noise, Vibration and Harshness quality.Read moreRead less
Convex optimisation for control, signal processing and communication systems. Renewable control of complex systems, signal processing, telecommunication and in general any industries interested in these applications stand to benefit from our research. In particular, the automotive and defence industries stand to benefit from the nonlinear control design aspect of the proposed project outcomes. The

In particular, the automotive and defence industries stand to benefit from the nonlinear control design aspect of the proposed project outcomes. The
telecommunications industries, on the other hand, benefit from the signal processing and communications aspects. We also build a core expertise in optimisation and its applications in Australia by training PhD students and Postdoctoral researchers. The research collaborations will cement and maintain the international linkages which will improve applied research in AustraliaRead moreRead less

The current success of the electronics industry rests on pillars made from the low cost, high performance and flexibility of silicon compounds. Silicon-based optics provides a new platform for the monolithic integration of optics and electronics. In this project, a multi-disciplinary team consisting of pioneers of nonlinear optics and siliconized photonics build a next-generation broadband silicon optical amplifier which can open the door to a new low-power, wide-bandwidth, high-speed and ultra-small optoelectronic devices. The technological advances arising from this project will provide Australia with critical capabilities for future commercial ventures and strengthen Australia's stake in the multi-trillion dollar semiconductor industry.Read moreRead less
Towards an Information Theory for Communication-Limited Control Systems. In a number of emerging applications in communications, manufacturing and defence, various dynamical systems are measured and controlled by transmitting feedback over digital communication channels. In such situations, the often limited data rate available for transmissions can have a significant negative impact on the overall objectives. This proposal aims to develop techniques for analysing and designing such systems, and ....Towards an Information Theory for Communication-Limited Control Systems. In a number of emerging applications in communications, manufacturing and defence, various dynamical systems are measured and controlled by transmitting feedback over digital communication channels. In such situations, the often limited data rate available for transmissions can have a significant negative impact on the overall objectives. This proposal aims to develop techniques for analysing and designing such systems, and to delineate the fundamental limits to their performance. This has the potential to contribute to a greater understanding of the behaviour of many real systems which combine communications and control in feedback loops.Read moreRead less
