Abstract
Passivity based control has several advantages, e.g., robustness and simplicity. However, the passivity constraint causes performance degradations. Specifically, the degree to which passively controlled absorber systems yield a flat response around the nominal absorber frequency is limited. An inherent flatness bound is derived using Nevanlinna-Pick boundary interpolation theory. For active vibration absorbers, this limitation cancels, and magnitude response can be made arbitrarily flat.
