Modal Control of Vibration in Rotating Machines and Other Generally Damped Systems (2006)
Conference Proceeding
Houlston, P. R., Garvey, S. D., & Popov, A. A. (2006). Modal Control of Vibration in Rotating Machines and Other 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...

Optimal Controller Designs for Rotating Machines - Penalising the Rate of Change of Control Forcing (2006)
Conference Proceeding
Houlston, P. R., Garvey, S. D., & Popov, A. A. (2006). Optimal Controller Designs for Rotating Machines - Penalising the Rate of Change of Control Forcing.

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.
