Method for controlling long-distance stable navigation of supercavitation navigation body

The invention provides a long-distance stable navigation control method for a supercavitation navigation body, and belongs to the technical field of supercavitation navigation bodies. The control method comprises the following steps: S1, acquiring the geometric shape and kinetic parameters of the supercavitation navigation body, and controlling a target; s2, establishing a dynamic model of the cruise supercavitation navigation body; s3, establishing a dynamic model of the underwater supercavitation navigation body; and S4, designing an underwater flat-turning and cruising stage control module, and controlling the navigation of the supercavitation navigation body by combining the underwater flat-turning and cruising stage control module with the cruising supercavitation navigation body dynamic model and the underwater supercavitation navigation body dynamic model. The problems that an existing supercavitation navigation body does not form a whole-process stable navigation control technology from water entry, f
