Abstract

Wide dynamic guided cannonballs need to be air-aligned after firing, and the precise acquisition of their initial roll angle has been a technical difficulty in the industry. In order to solve the problem that the driveless MEMS gyroscope cannot calculate the initial roll angle on a gentle trajectory, and the attitude information obtained by solving only the crest point is too few, this paper proposes a combined measurement scheme of driveless MEMS gyroscope and accelerometer based on adaptive complementary filtering technology, and the extended Kalman filter and Hilbert transform are used to solve the attitude calculation, which can obtain comprehensive attitude information and solve the problem of gentle trajectory attitude measurement of guided projectile. Both theoretical curve analysis and experimental results analysis prove the effectiveness of the method in this paper.
