    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.
