The importance of exploring Mars is self-evident, Mars's extremely low atmospheric density, resulting in Mars drones must have enough light weight. Multi-rotor unmanned aerial vehicle (UAV) with flexible racks offer another possibility for the lightweight design of Mars Rotorcraft. Based on the unique atmospheric environment of Mars, a flexible rotorcraft with ultra-light structure is designed in this paper, and the stability control of this flexible UAV is studied. A compound stability augmentation control system is proposed, which adopts PID controller as the main controller and L1 adaptive controller as the composite controller with output feedback to realize the stable flight of flexible Mars UAV. And through the flight experiment, it is proved that the designed controller has a good stability control effect for the flexible Mars UAV.
