Experimental robust control of structural acoustic radiation

Abstract: This work addresses the design and application of robust controllers for structural acoustic control. Both simulation and experimental results are presented. H ∞ and µ-synthesis design methods were used to design feedback controllers which minimize power radiated from a panel while avoiding instability due to unmodeled dynamics. Specifically, highorder structural modes which couple strongly to the actuator-sensor path were poorly modeled. This model error was analytically bounded with an uncertainty model, whi… Show more
