To solve the vibration problem of model support system in wind tunnel test, a support cantilever structure was designed, which was integrated with piezoelectric package used as damping element.The dynamics equation of the support cantilever was established.And the state equations for system identification through the neural network arithmetic and classic PID arithmetic were deduced.Meanwhile, according to rigid-flexible coupling dynamics theory the structure vibration simulation model of model support system was built.
