Dynamics of a Nonsmooth Supercavitating Vehicle System
As a representative example of a C continuous system, a four-dimensional model of the dive-plane dynamics of the supercavitating body shown in Figure 1 is considered. This model includes a dominant, nonsmooth nonlinearity associated with the planing force [1,2]. The original non-smooth system is approximated by a smooth counterpart, and it is examined as to how well the smooth system captures t...
متن کاملStudy of the Dynamic Stability of an Underwater Vehicle
The problem of dynamic stability of motion of underwater vehicles is addressed by developing an analytical model of the underwater vehicle dynamics and by applying it using a simulator. The model’s equations of motion were obtained by combining theoretical formulae with experimental data, taking into account the coupling between the different forces and moments produced on the submersible by th...
متن کاملA Dynamic Test Platform for Evaluating Control Algorithms for a Supercavitating Vehicle
The use of supercavitation to enable marine vehicles to travel at extraordinary speeds is a topic of considerable interest. The control of these vehicles poses new challenges not faced with fully wetted vehicles due to a complex interaction between the vehicle and the cavity that it rides in. Some of the existing models make assumptions that may not be valid for a maneuverable vehicle. Furtherm...
متن کاملMulti-vehicle Dynamic Pursuit Using Underwater Acoustics
Marine robots communicating wirelessly is an increasingly attractive means for observing and monitoring in the ocean, but acoustic communication remains a major impediment to real-time control. In this paper we address through experiments the capability of acoustics to sustain highly dynamic, multi-agent missions, in particular range-only pursuit in a challenging shallow-water environment. We p...
متن کاملDynamic Simulation of Underwater Vehicle Manipulator Systems
Control of Underwater vehicle manipulator systems (UVMS) are limited to human intervened tele operation in almost all practical applications. Extending these missions to autonomous or semi autonomous operation requires accurate dynamic modeling of the system. Such modeling assists system design and controller testing of autonomous UVMS. The study performs a dynamic analysis to capture relative ...
