摘要
在无人机的飞行控制中,飞行高度是重要的控制参数。基于数字压力传感器MS5534研制的高度传感器,对大气压力进行了温度补偿,用软件滤波兼顾了数据稳定性和频率响应,采用气压-高度的分段非线性拟合保证了精度,并结合飞控系统设计了通信接口。该高度传感器具有体积小、质量轻、数据稳定、响应快的优点,特别适合无人机的使用,经某型号无人机飞行试验,完全满足飞行控制系统的要求。
Flight altitude is an important controls parameter in the control of UAV. The altitude sensor based on digital pressure sensor MS5534 equalized the temperature to atmospheric pressure, considered both data stability and frequency response by software filter, assured the precision by air pressure-altitude subsection nonlinearity conformity, and designed the communication interface integrated with flight control system.The sensor which is noted for its small volume.hght weight,data stability,fast response is fit to the use of UAV. According to experimentation of a certain UAV, it can meet the requirement of flight control system.
