REVIEW OF DYNAMICS AND CONTROL OF STRATOSPHERIC AIRSHIPS

The developmental history and research status of airship are briefly presented. Compared with the traditional aircraft, spacecraft, submarines and low altitude airship, the flight principle of stratospheric airships is elaborated. From the point of view of basic motion model and the complex force condition, progresses in dynamics research are discussed systematically, including aerodynamics research, static analysis, thermodynamic analysis, flexible body dynamics and the study of fluid-solid coupling. Then the progress in airship control methods is reviewed, including the small disturbance linearization control, input output feedback linearization control, the Lyapunov nonlinear stability based control and other control method. Finally, it is proposed to reinforce research efforts in six directions in the field of stratospheric airship dynamics and control.
