While the arrangement does indeed seem to work, the analysis is less than rigorous. I am not certain how to accommodate the fact that imbalance mass and resonant motion are seperated by a phase angle. Below resonant speed however, the two are in phase and I am supposing it is during this period that the correction happens. I haven't sat down and really considered it carefully - any takers?
Cheers Richard
