A new concept of control accelerated motion of supercavitating vehicle is present. Before reaching a constant cruising speed of 100 m/s supercavitating vehicle is process of accelerated motion. In order to explore dynamic model and control challenges associated with the longitudinal accelerated motion of supercavitating vehicles, memory effect of the cavity and its influence on shape of cavity are researched based on the principle of cavity expansion independence. Efficiency of the fin as its immersion depth changes while the vehicle is traveling underwater is researched. A gain schedule controller is designed to stabilize the dive-plane dynamics during accelerated motion of supercavitating vehicle.
