The invention relates to a comprehensive control method for keeping a fixed-point height of an airship in the stratosphere, which is used for keeping the fixed-point height of the airship in the stratosphere by adopting a combined mode of pressure adjustment and thrust vector. The method has the advantages of small fluctuation range of the fixed-point height and great corresponding reduction of the reserve volume of an auxiliary ballonet. To be explained, the application of the thrust vector does not increase extra energy consumption because the airship in the stratosphere always keeps a certain thrust in a fixed-point flight in order to overcome the wind resistance; According to the method, only the direction of the thrust is changed and an increased net buoyancy is balanced by utilizingthe component in the vertical direction, which can result in that the component in the horizontal direction cannot overcome the wind resistance so that the position precision of the airship in the stratosphere in the horizontal direction cannot be kept; however, in terms of engineering application, the expense of a little horizontal positioning precision is worthy because the fixed-point height position of the airship in the stratosphere is far more important than the horizontal position precision thereof; and the airship in the stratosphere can flexibly fly to a fixed-point position once thetemperature returns to normal.
