Abstract
Active control of vibration by minimisation of total supplied
power is an attractive approach from a theoretical point of view.
In this practical study of the method two secondary sources were
applied to control the sinusoidal excitation of an aluminium beam
from a single primary source. The control algorithm was able to
reduce the total supplied source power in a frequency band ranging
from 50 to 500 Hz. The algorithm is surprisingly insensitive to
measurement errors. However, very precise estimates of the power
from the individual sources are required to quantify the total
supplied power.
