摘要
研究了一种利用多只低灵敏度的微机电系统(MEMS)重力加速度传感器实现对飞行器姿态识别的方法。通过对MEMS加速度传感器的输出信号进行A/D采样,获得相应的数字信号,并将其送进单片机进行处理,实现对飞行器的仰角和倾角的高精度测量,最终得到飞行器的姿态信息。该方法可实现-180°^+180°范围内的倾角值测量,即使飞行器在旋转时也能进行实时测量,可用于需要进行姿态控制的各类飞行器的实时姿态识别。
This paper studies a method of identification about the aircraft＇s attitude by using several low-sensitivity MEMS accelerometers of gravity. When the output analog signals came from the MEMS accelerometers, sampling them into digital signals and processed them with MCU, then system could get the value of inclination and elevation angle with high precision. It is pointed that MCU systems could measure the value of inclination angle at the range of -180°～＋ 180° even if the aircraft were circumvolving. The results indicate that this method can be used to determine the attitude of aircraft which needs to be controlled.
