Simu2VITA: A General Purpose Underwater Vehicle Simulator

Area of Science:

• Robotics
• Ocean Engineering
• Control Systems

Background:

• Developing realistic simulation tools is crucial for advancing Unmanned Underwater Vehicle (UUV) technology.
• Existing simulators may lack ease of use, rapid setup, or parameter modification flexibility.
• Accurate vehicle dynamics simulation is essential for effective controller design and mission planning.

Purpose of the Study:

• To present Simu2VITA, a novel simulator for Unmanned Underwater Vehicles (UUVs).
• To design Simu2VITA for rapid setup, ease of use, and straightforward parameter modification.
• To validate the simulator's effectiveness by comparing simulation results with real-world UUV mission data.

Main Methods:

• The simulator, Simu2VITA, was developed within the MATLAB/Simulink framework.
• Vehicle dynamics simulation is modularized into Actuator, Allocation, and Dynamics Modules.
• The Actuator Module simulates components like propellers and fins.
• The Allocation Module translates actuator actions into forces and torques.
• The Dynamics Module implements the vehicle's rigid-body dynamics equations.

Main Results:

• Simu2VITA successfully simulated UUV dynamics, including actuators and rigid-body motion.
• Simulation results for a tunnel navigation mission were generated.
• These simulation results were compared against sensor data from the actual UUV performing the same mission.

Conclusions:

• Simu2VITA provides a useful and validated platform for UUV simulation.
• The simulator aids in designing and testing controllers for UUVs.
• The comparison with real-world data confirms the simulator's accuracy and utility for UUV development.
