Controlling of a supercavitating vehicle has been confronted with various challenging problems such as the potential instability of the vehicle, the unsteady nature of cavity dynamics, and the complex and non-linear nature of the interaction between vehicle and cavity. The vehicle model in the dive plane is given. From complex nonlinear model, a multiple inputs and outputs linear system is obtained...
Because of super-cavitation, there is no buoyancy force to balance the gravity of super-cavitating vehicle. In addition, there exists the nonlinear planing force on the vehicle. The motion of vehicle in the vertical plane tends to be unstable and the dynamic model of it is complicated and nonlinear. By introducing a feed-forward compensation and nonlinear state feedback, the nonlinear system could...
This paper considers the path tracking problem for a class of underactuated autonomous underwater vehicles (AUVs), where only surge force and stern plane are available for vehicle's 3DOF diving motion. For these torpedo-type flying vehicles, the pitch moment is proportional to the vehicle's forward speed. Therefore, if vehicle takes slow motion, then we cannot fully excite the vehicle's pitch motion...
