MISSILE AND OPERATING METHOD THE SAME HAVING ROLL VIBRATION RESTRAINER

摘要

PURPOSE: A flying object including a roll vibration damping device and a driving method thereof are provided to enable precise induction and control by suppressing roll vibration with a multi filter using a different kinds frequency estimating device. CONSTITUTION: A flying object including a roll vibration damping device comprises a band passing filter(111), a frequency estimating device(112), and a notch filter(113). The band passing filter passes a roll rate signal of the flying object in a predetermined frequency band for filtering. The frequency estimating device estimates a signal of a predetermined vibration frequency band in a roll vibration sensing signal. The notch filter uses frequency and a reduction coefficient and filters control command of the flying object. [Reference numerals] (130) Controller
