Recently, research on the flight control of indoor small unmanned airships has attracted much attention. Unmanned airship has characteristics of low manufacturing cost, long dwell time, low energy consumption and so on. Under the premise of ignoring the external wind interference, a controller is designed that makes the airship move to the preset point and stay in the air. The mathematical model of the unmanned airship is first introduced in this paper. A six-degree-of-freedom equation of motion is established after force analysis, and then it is simplified to a three-degree-of-freedom model according to the geometric symmetry of the airship. Subsequently, the motion process of the airship is disassembled into horizontal motion and vertical motion, the backstepping method is used to design the controller, and unknown parameters in the model are processed with adaptive control. Finally, computer simulation experiments are carried out to verify the correctness of the model and the effectiveness of the controller from a mathematical point of view. In this paper, a small unmanned airship motion control system is designed, and its feasibility from the perspective of computer simulation is verified. These studies provide initial exploratory work on control methods for indoor unmanned airships.
