abstract

A dive-plane model of a supercavitating vehicle is considered and the physical basis for a time delay effect in this system is described. The time delay is on the order of the vehicle length divided by its speed. Control design is carried out to achieve stabilization of the supercavitating vehicle for trim conditions inside or outside the cavity in the presence of the time delay effect. The effectiveness of different control designs are demonstrated by carrying out numerical simulations with the nonlinear dive-plane model of the supercavitating vehicle. A preliminary investigation conducted into the utilization of an outer-loop controller for vehicle maneuvering is also presented. A numerical optimal control approach is used to study dive, move-to-point, and obstacle avoidance maneuvers of the delay-free system.
