Abstract

Most damping controller designs are based on, and aimed at, damping the first dominant resonant mode of the targeted system. The higher-order dynamics of these systems are left unmodeled and an adequate feed-through term is generally added to compensate for model truncation effects. The Integral Resonant Control (IRC) exploited this feed-through term to manipulate the dynamics of resonant colocated systems such that a simple integrator delivered adequate damping to the resonant mode. As an added advantage, IRC also imparted damping to other higher-order modes and was guaranteed stable. Nevertheless, this was still a single-mode based design. In this paper, we formalize the effect of the feed-through term on a typical multi-mode system and present the design and analysis of a true multi-mode IRC.
