A nonlinear feedback is used to implement the transformation of states and control variables, and the minimum-phase system property is adopted in building the feedbacklinearized dynamic model for the airship. On this basis, we investigate the feasibility and the stability of the equilibrium flight of the airship in a longitudinal plane, and the stabilization of the equilibrium flying paths as well as the tracking of the desired outputs. The simulation results and the prototype test results verify the theoretical analysis and confirm the reliability. %K airship dynamics modeling %K ballonets and ballast %K feedback control %K equilibrium paths %K zero dynamic %K minimum phase system
