Mitigating whirl flutter in a tiltrotor aircraft includes providing at least one control surface supported for movement relative to a pylon attached to the aircraft's wing; providing an actuator for moving the control surface relative to the pylon; providing at least one sensor system to sense at least one deformation mode of the wing tip; providing a control system having one or more inputs and one or more output signals; using an electrical signal relating to deformation of the wing tip to serve at least as the basis for at least one of the inputs to the control system; determining at least one output signal of the control system based at least in part on the electrical signal relating to deformation; and controlling the actuator based at least in part on the output signal of the control system to move the control surface so as to counteract the deformation.
