Optimal Controller Designs for Rotating Machines - Penalising the Rate of Change of Control Forcing (2006)
Presentation / Conference Contribution
Houlston, P. R., Garvey, S. D., & Popov, A. A. Optimal Controller Designs for Rotating Machines - Penalising the Rate of Change of Control Forcing. Presented at 7th IFToMM Conference on Rotor Dynamics

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
Presentation / Conference Contribution
Bertola, L., Cox, T., Wheeler, P., & Garvey, S. D. Superconducting and conventional electromagnetic launch system for civil aircraft assisted take-off. Presented at IEEE Energy Conversion Congress & Expo

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...

Modal Control of Vibration in Rotating Machines and Other Generally Damped Systems
Journal Article
Generally Damped Systems

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...
