To realize the smooth transition of balance of motion and quiescence of aircrafts and satisfy the cruise requirement of level flight above specific points,the flight processes of a Mars vehicle are analyzed and a longitudinal model of the Mars vehicle is established. The motion characteristics of pull level flight processes of the Mars unmanned aerial vehicle are researched, and the control difficulties of pull level flight processes are summarized. A mode switching control method with variable control structure and control parameters is used to achieve the effective control of pull level flight processes of the Mars unmanned aerial vehicle. The simulation results show that the method proposed here is feasible.
