title = "Robust flutter control of an airfoil section through an ultrasonic motor",
abstract = "The paper presents how to realize the robust flutter suppression of an airfoil section through the control surface driven by an ultrasonic motor. The study starts with the combined theoretical and experimental modeling for the aero-servoelastic system with the damping uncertainties in plunge, and the modeling error of the servo, taken into consideration. Then, it turns to the design of the H∞ controller and the μ-synthesis controller at a given flow speed. The numerical simulations and wind tunnel tests show that both controllers are able to suppress the airfoil flutter effectively, and increase the flutter speed by 23.4\%. In addition, the μ-synthesis controller works better than the H∞ controller not only in the suppression rate, but also in the robustness with respect to the time delay in the control loop.",
