  • This paper investigated the vibration suppression systemfor vertical tail. Firstly, the actuators and sensors were divided into twogroups according to the results of modal tests, and attached to the oppositeside of vertical tail with a mirror image. To overcome the unstable problemcaused by the coupling of output signal and reference signal, a feed forwarddecoupling algorithm was proposed. Finally a smart vertical tail wasdesigned to reduce the fatigue damage through suppressing its vibration. Theexperimental results showed that the vibration response of vertical tail wassuppressed significantly.
