    Abstract
  • Anti-aircraft missile are always designed with large aspect ratio,which has low body flexible frequency. Besides, nozzle swing would increase the vibration of missile body. To eliminate this effect, the article analyzed the relationship between the vibrations and control system. Based on modeling of flexible missile, it proposed the layout of the dual sensor plan and the way of pre-integrating for signal preprocessing. Using a new adaptive notch filter basing on Steiglitz-McBride, the useful signal could be got from the rigid body motion of the missile. In this way, the control system would have more flexibility and adaptability while dealing with the aeroservoelasticity. What's more, the layout of dual sensor would increase the reliability of measure and filter at the same time.
