A Segmented Interior Permanent Magnet Synchronous Motor for Wide Field Weakening Range and its Sensorless Control using Improved Flux Estimators. Australia has the world's second largest reserve (after China) of high energy-density permanent magnet (neodymium-iron-boron) material for the IPM motor. The present limitation of the machine to be driven sensorless over a wide speed range with field weakening is believed to be holding back its widespread use in applications other than servo-type which ....A Segmented Interior Permanent Magnet Synchronous Motor for Wide Field Weakening Range and its Sensorless Control using Improved Flux Estimators. Australia has the world's second largest reserve (after China) of high energy-density permanent magnet (neodymium-iron-boron) material for the IPM motor. The present limitation of the machine to be driven sensorless over a wide speed range with field weakening is believed to be holding back its widespread use in applications other than servo-type which requires high-resolution mechanical sensors. Extension of the motor speed range by a combination of magnetic system design (for large field weakening range), and sensorless position and flux estimation with sufficient accuracy for fast dynamic control should lead to large scale adoption of this motor, and hence to significant improvement in energy efficiency and market share for Australia.Read moreRead less
Towards a unified theory of constrained control and estimation. The project will investigate the implications of duality and other connections between constrained control and estimation. We believe that the research will result in a richer understanding of these problems. In particular, we envisage an impact in at least four areas: (i) Computational issues, i.e., development of more efficient algorithms for constrained problems. (ii) Geometry of constrained problems, by extending recent results ....Towards a unified theory of constrained control and estimation.

We believe that the research will result in a richer understanding of these problems. In particular, we envisage an impact in at least four areas: (i) Computational issues, i.e., development of more efficient algorithms for constrained problems. (ii) Geometry of constrained problems, by extending recent results pertaining to constrained control to estimation problems.
