针对以往三轴磁传感器和加速度计组合测量高转速弹体姿态的不足,提出了一种新的姿态测量方案。该方案由两个磁传感器和两个加速度计以特定的方式安装及相应的解算方法组成。说明了传感器的布阵方式,并给出了弹体姿态解算的数学模型和解算方法。该解算方法包括Magsonde Window和最值之比的证明以及姿态角解算的理论分析,最后对此方案进行了建模与仿真。仿真结果表明,解算的姿态角与真实姿态角相符。
Aiming at the shortcomings of the combination of three-axis magnetic sensor and accelerometer to measure the attitude of high-revolving projectile, a new attitude measurement scheme is proposed. The program consists of two magnetic sensors and two accelerometers installed in a specific way and the corresponding solution method. The deployment of sensors is described and the mathematical model and solution method of missile attitude solution are given. The solution includes the proof of Magsonde Window and the ratio of maximum value and the theoretical analysis of attitude angle solution. Finally, the scheme is modeled and simulated. Simulation results show that the calculated attitude angle is in accordance with the real attitude angle.
