Determining the Coupling Source on a Set of Oscillators from Experimental Data

摘要: Complex systems are a broad concept that comprises many disciplines, including engineering systems. Regardless of their particular behavior, complex share similar behaviors, such as synchronization. This paper presents different techniques for determining the source coupling when set oscillators synchronize. It is possible to identify location and time variations by applying combination analytical techniques, namely, For this purpose, analysis experimental data from mechanical system presented. The experiment consisted in placing 24-bladed rotor under an airflow. vibratory motion blades was recorded with accelerometers, resulting information analyzed four techniques: correlation coefficients, Kuramoto parameter, cross-correlation functions, recurrence plot. measurements clearly show existence frequencies due foreground components internal interaction between them background (coupling).
