Active Control of String Instruments using Xenomai

Real time system is a necessary component of an active control implementation. For example, the sound control, which became a real issue in a lot of fields, needs deterministic and fast properties. This research study presents an application using the Xenomai framework in order to control the vibration of a string instrument’s soundboard. A control system is designed and applied to this structure with the aim of changing the instrument sound. The acquisition board used to measure and send the signals on the soundboard is linked to a modeling software running under the Xenomai real time framework, ensuring the necessary active control properties.
