Reference Matrix for Multi-Axis Random Vibration Control Tests

The advantages of performing Multiple-Input Multiple-Output (MIMO) Random
Vibration Control tests are widely accepted by the environmental engineering
community. The purpose of this work is to investigate more innovative target
generation procedures pointing out the advantages and the challenges in terms of
physical meaning and their impact on the random control strategy, in order to aim to a well-defined automatic procedure to be included in the standard practice.
