摘要
基于微机电系统(micro-electro-mechanical system, MEMS)惯性传感器的MEMS惯性导航技术是近年来惯性导航领域的研究热点和未来主要发展方向之一,也是无人系统自主导航进而实现智能自主控制的一项关键技术。文章概述了MEMS惯性传感器的分类以及国内外发展概况,介绍了MEMS惯性导航的两项关键技术——MEMS惯性传感器的误差补偿技术和基于MEMS惯性导航的组合导航算法,阐述了MEMS惯性导航技术在无人机、无人车、无人船及机器人等代表性无人系统中的应用,最后展望了MEMS惯性导航技术的发展和应用前景。
MEMS inertial navigation technology based on micro-electro-mechanical system(MEMS) inertial sensors is a research hotspot in recent years and one of the main future development directions in the field of inertial navigation. It is also a key technology for autonomous navigation of unmanned systems to realize intelligent autonomous control. In this paper, the classification of MEMS inertial sensors and the overview of domestic and foreign development were introduced. Then, two key technologies of MEMS inertial navigation--the error compensation technology of MEMS inertial sensors and the integrated navigation algorithm based on MEMS inertial navigation were described. Furthermore, the applications of MEMS inertial navigation technology in representative unmanned systems such as unmanned aerial vehicle, unmanned ground vehicle, unmanned ship and robot were summarized. Finally, the development and application prospects of MEMS inertial navigation technology were forecasted.
