Modelling and minimising energy consumption in ring spinning. Australia's 4-billion dollar natural fibre production is spun into yarns via ring spinning mainly. A major drawback of this spinning system is its high energy consumption. This project will examine, theoretically and experimentally, the key factors contributing to energy consumption in ring spinning. It will generate new knowledge on the relationship between yarn hairiness and the air drag on a rapidly rotating yarn package and on a b ....Modelling and minimising energy consumption in ring spinning. Australia's 4-billion dollar natural fibre production is spun into yarns via ring spinning mainly. A major drawback of this spinning system is its high energy consumption. This project will examine, theoretically and experimentally, the key factors contributing to energy consumption in ring spinning. It will generate new knowledge on the relationship between yarn hairiness and the air drag on a rapidly rotating yarn package and on a ballooning yarn, and predict how this air drag affects the energy consumption during package build-up in ring spinning. This will lead to ways of minimising energy consumption in this most important spinning process.Read moreRead less
Real time optimisation by extremum seeking control and learning control. Optimal control technology provides the systematic design of systems that exhibit optimal behaviour, such as maximal productivity, best efficiency, minimal cost and best quality.

Extremum seeking control: analysis, design and applications. Optimal control is one of the central pillars in the field of automatic control, but is prevented from use in many engineering applications due to the computational complexity and system knowledge requirements typically associated with the technique. Extremum seeking promises the performance of an optimal approach, but with the benefit of real time implementation and very relaxed requirements on the system knowledge. Through improved u ....Extremum seeking control: analysis, design and applications.
