Abstract(s)
Structural control includes a wide variety of control methodologies that have been
developed over the years to deal with specific problems of civil engineering
applications. In this regard, magneto-rheological (MR) dampers seems to be a
promising technology to develop semi-active control systems for vibration control of
building and bridge structures. Although the application of these devices in actual
structures is still emerging, its efficiency to reduce high winds and seismic-induced
vibrations has been validated through numerous numerical simulations,
experimental tests either in reduced and full scale models and also some real
applications. A major challenge of this type of control system is related to the choice
of suitable control algorithms that allow the specific features of these controllable
devices to be fully exploited. Thus, this paper provides an overview of the
fundamental control algorithms usually involved in developing semi‐active
controllers with MR dampers for vibration suppression in civil engineering
structures. The operating principle of each controller is briefly described specifying
for each case the main requirements and also the fundamental control parameters
that must be defined during the development of a semi‐active control system with
MR dampers.
