Combined State and State Derivative Control Applied to Musical String Instruments
Résumé
In the following study, the state derivative control is used to complete the usual state control. This combined method allows the control of the vibration amplitude of a structure while ensuring the stability of the feedback loop. Firstly, this article presents the approach which leads to development of a combined control method. Then, simulations are presented in trivial examples to illustrate this method. Finally, an application on simulated simplified soundboard is tested and advantages and difficulties linked to the use of this method on an experimental case are shown.
