摘要
在小型无人直升机的控制中,需要有高精度的运动测量信息作为导航状态输入,通常这些小型直升机因需要在特定的情况下工作而往往体积较小,因而也对导航设备提出了高精度、低功耗、微型化、低成本等多方面的苛刻要求。介绍一种基于MEMS器件的小型姿态航向参考系统的设计及实现,该系统已应用于小型无人直升机的导航控制中。
To control a small unmanned helicopter, high precision information of motion is supplied to control system as navigation states. But the small unmanned helicopter often works at especial conditions so that they have miniature body. Therefore, it incurs a high demand on high precision, low energy consumption, miniaturization and low cost of navigation system. The design and imple- mentation of a tiny attitude and heading reference system based on MEMS units is discussed, and the system has been embedded in the navigation/flight control system of a small unmanned helicopter.
