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...
