KONTROL VIBRASI AKTIF PADA STRUKTUR YANG MENGALAMI BEBAN DINAMIK DENGAN MENGGUNAKAN JARINGAN SARAF TIRUAN DAN ALGORITMA GENETIK
ABSTRACT: This paper
presents an active
control technique applied
to building structures
which are excited
by external dynamic loadings
such as earthquake,
wind, and blasting. By
using the active
control system, the
structural vibration responses can
be decreased by
giving control forces
generated by actuator
which is based
on the responses
of the structure. The control
forces given to the structure are calculated by using genetic algorithm theory.
The actual external loadings and the responses of the structure are measured by
using dynamic sensors and placed at certain location on the structure.“Smart
Structure” concept which is proposed in this paper is an efficient way in
conceiving and designing an earthquake
resistant building. This
concept imitates the
human neural system,
where inside the human
body there are sensors
and energy against
external excitation or disturbances.The application
of this system
for building structures, requires a fast and accurate
calculation of control forces, so that time delay in giving control forces to
the structure will be minimized . This
requirement can be
achieved by using
combination of an
Artificial Neural Network
method and Genetic Algorithm
approach.
