... and experimental studies have been conducted over many years to develop strategies for modeling and controlling the behavior of this class of vibration dampers, no guidelines currently exist for determining optimum strategies for maximizing the performance of particle dampers, whether in a single unit or in arrays...

...Guoxin Li; Zongli Lin; Paul E. Allaire; Jihao Luo This paper reports on the modeling and experimental identification of a high speed rotor-magnetic bearing test rig. An accurate nominal model and an uncertainty representation are developed for robust controller synthesis and analysis. A combination...

... with the assignment to write such a search program to find the zero crossings of the characteristic determinant. The introduction to lateral analysis starts with a review of the Jeffcott model for a single mass rotor, followed by the extended Jeffcott analysis 17 . Then the students are introduced to the Prohl...
