Maneuver Control Method of Supercavity Vehicle Based on Active Bank-To-Turn

To raise the mobility of the supercavity vehicle, a maneuver control method based on active bank-to-turn(BTT) is established in this paper. After analyzing the hydrodynamics of the supercavity vehicle, the gliding force coefficient and moment coefficient tables are solved according to the wetting status of the vehicle under different working conditions, and the sliding force is reconstructed. A six-degree-of-freedom dynamic model of the supercavity vehicle is established. According to the up-and-down rudder control mode, the proportional-integral-derivative(PID) controller of depth and roll channel of the supercavity vehicle is designed. Thus, a maneuver control method based on the active BTT control strategy is proposed. Mathematical simulation results show that the designed controller has good dynamic characteristics, and can meet the requirements of the supercavity vehicle for maneuver. The method established in this paper can be referenced for maneuver realization of supercavity vehicle with single-degree-of-freedom cavitator.
