摘要

In the future, the application of unmanned aerial vehicle to detect Mars is an important research direction of deep space exploration. In this paper, design methods of automatic flight control system for Mars airplane based on total energy theory are proposed, and the main works include the calculation of balance states, the analysis of dynamic characteristics, the design of the control system and the implementation of the smooth transition process at the different flight stage such as the gliding, pull-up and level flight. In addition, atmospheric environments on Mars and on Earth are compared, and in the different flight conditions trim flight states are acquired and aerodynamic characteristics are analyzed contrastively. Further the control law for Mars airplane based on total energy principle is presented, and complicated multiple-input-multiple-output control system is established. Finally analysis results verify the effectiveness of the method, at the same time show the automatic flight control law can realize the autonomous flight process for unmanned aerial vehicle on Mars, and can also ensure the robustness of the system in the Martian atmospheric environment.
