Abstract:

 Unmanned aerial vehicle for Mars exploration is a development direction in the future deep space exploration. In this paper, modeling and switching of Mars vehicles are studied. The flight process of the vehicle is briefly described, and a mathematical model established. The steady state performance is analyzed under conditions with and without a parachute. Systems for controlling position and altitude are designed, and switching control is realized. Simulation shows that the model is stable and feasible, and the proposed switching control methods can guarantee security and stability of the switching process.

Key words: unmanned aerial vehicle, mars exploration, switching control, stable performance
