Abstract: |
The
Searazor is a novel underwater
vehicle designed for underwater inspection and maintenance of ships and underwater
structures. In this paper, the vehicle’s dynamic characteristics and control
scheme are studied. A series of sub-models, representing the major components
of the vehicle, are developed in a bond graph environment. A servo control
system that governs the attitude and steering is also implemented. These models
are then assembled and operated as a rigid body under the force input from
thruster, wheels and environmental factors. The resulting motion of the vehicle
under human manoeuvring input is simulated in 20sim
software. Analyses and simulations are also implemented for dynamic stabilisation under disturbance from waves and current.
The simulation currently provides support for Searazor
prototype design. The entire model will be the simulation framework for
developing and testing control algorithms to maneuvre
the vehicle in complex marine environments. |
