Abstract

The traditional approach to minimizing structural vibration implements either passive dampers or global model-based active controllers. Unfortunately, passive control becomes massive for control of low frequency disturbances. Model-based active controllers are difficult to apply to complex structures, because the model needs to be of roughly the same order as the system that it describes in order to achieve robust performance. Modeling errors due to mismodeled dynamics, missed dynamics, or time-varying dynamics can be performance degrading and potentially destabilizing [6]. This paper focuses on the lightly damped and modally dense systems where modeling errors are more significant.
