An improved vibration and disturbance reduction method for a quad-rotor micro air vehicle

This paper focuses on the vibration and disturbance reduction method for a quad-rotor micro air vehicle. A hanging structure of vibration isolation is proposed, modelled and analyzed. The results show that it can attenuate the high-frequency vibration and eliminate zero drift of the accelerometer effectively. A simple attitude measurement strategy which can reduce the disturbance of the inertial sensors is also presented.
