Abstract:
|
In this work, a systematic strategy to design
passive damping systems for structural vibration control is
presented. The proposed design methodology is based on
the equivalence between decentralized static velocity-feedback
controllers and passive damping systems. By using recent developments
in static output-feedback control, the design of passivedamping
systems can be formulated as a single optimization
problem with Linear Matrix Inequality constraints. Moreover,
this optimization problem can be efficiently solved with standard
numerical tools, even for large dimension systems. Due
to its computational effectiveness, the proposed methodology
can be applied to the design of passive damping systems for
large structures. To illustrate the main ideas and methods, a
passive damping system is designed for the seismic protection
of a five-story building with excellent results. |
