Convair B-58 Hustler

Not directly related to the B-58, but the B-1 uses the two small canards near the cockpit and lower rudder section to control fuselage flex as part of its Structural Mode Control System to reduce fatigue stress and improve the crew ride. Quite possible this was a lesson learned from the B-58 experience.
And tested (sort of) on the NASA XB-70 and YF-12A with "shaker" vanes.

"The XB-70 was fitted with two small vanes for the Identically Located Acceleration and Force (ILAF) experiment. The vanes rotated 12 degrees at a rate of up to 8 cycles per second. This induced a structural vibration in the XB-70 at a known frequency and amplitude. The XB-70’s accelerometers detected the disturbances, then signaled the aircraft’s stability augmentation system to damp out the motion. When XB-70 research flights resumed on June 11, 1968, the ILAF proved its ability to reduce the effects of turbulence and atmospheric temperature changes."
