摘　　要：利用无人机进行火星探测,具有探测范围广、可看到地形变化等优点.介绍了火星探测无人机总体任务规划的情况,讨论了探测无人机在火星与地球上飞行的区别,建立了火星探测无人机纵向非线性模型,并在平衡点对非线性模型进行泰勒展开,得到线性化模型.通过对线性模型的进一步分析,掌握了火星探测无人机的稳态性能及飞行特点.With the development of socio-economy and technology, more and more people from various countries pay more attention to deep-space exploration. Mars is the closest planet where life is possible. So, Mars exploration is a hot issue on international deep space exploration in recent years. There are many advantages for the use of unmanned aerial exploration vehicles on Mars, including the wide range of exploration, the visualization of terrain changes, etc. In this paper, the overall mission planning is described for unmanned aerial exploration vehicle on Mars, and the difference between flight on earth and on Mars is discussed. Then the longitudinal nonlinear model is established for unmanned aerial exploration vehicle on Mars, and Taylor expansion is applied to the nonlinear model at the trim point, hence to obtain the linear model. By further analysis of the linear model, the stable performance and flight characteristics have been grasped for unmanned aerial exploration vehicle on Mars. These work will provide the platform for the follow-up research for Mars Unmanned Aerial Vehicle （UAV） navigation and control method.
