Design study and scaled experiment of induction and synchronous motor for civil application of electromagnetic aircraft launch system (2016)
Conference Proceeding

The engine size of modern passenger transport aircraft is principally determined by take-off conditions, since initial acceleration requires maximum engine power. An Electromagnetic Launch (EML) system could provide some or all of the energy required...

Modal Control of Vibration in Rotating Machines and Other Generally Damped Systems (2006)
Conference Proceeding

Second order matrix equations arise in the description of real dynamical systems. Traditional modal control approaches utilise the eigenvectors of the undamped system to diagonalise the system matrices. A regrettable consequence of this approach is t...

Optimal Controller Designs for Rotating Machines - Penalising the Rate of Change of Control Forcing (2006)
Conference Proceeding

In the context of active control of rotating machines, standard optimal controller methods enable a trade-off to be made between (weighted) mean-square vibrations and (weighted) mean-square currents injected into magnetic bearings. One shortcoming of... Read More about Optimal Controller Designs for Rotating Machines - Penalising the Rate of Change of Control Forcing.

Superconducting and conventional electromagnetic launch system for civil aircraft assisted take-off
Conference Proceeding

This paper compares three possible linear motor topologies for an electromagnetic launch system to assist civil aircraft take-off. Assisted launch of civil aircraft has the potential of reducing the required runway length, reducing noise and emission...
