Modeling and Control of Underwater Vehicle: Sparus AUV

Overview

This project is dedicated to the modeling, analysis, and control of the Sparus Autonomous Underwater Vehicle (AUV) under the supervision of Prof. Mathieu Richier at the University of Toulon. Utilizing MATLAB and Simulink, this project encompasses a comprehensive examination of the Sparus AUV's physical properties, hydrodynamics, and control mechanisms.

Objectives

• Dimensional Analysis: Compute dimensions of various components of the Sparus AUV based on provided schematics.
• Mass Matrix Analysis: Elucidate the global real mass matrix terms, tracing their origins to specific AUV components.
• Magnitude Analysis: Analyze the orders of magnitude of mass matrix terms to derive significant insights.
• Added Mass Computation: Calculate added mass matrices at the Sparus AUV's buoyancy center, excluding the main body.
• Matrix Comparison: Evaluate the differences in matrices calculated at the Center of Gravity (CG) and Center of Buoyancy (CB) and assess the impact of their spatial separation.
• Component Comparison: Contrast the physical and hydrodynamic properties of the main solid body against other components.
• Mass Matrix Evaluation: Compare added and real mass matrices to conclude on their relative impacts.
• Drag Matrix Estimation: Estimate all drag matrices for the Sparus AUV.
• Simulation and Validation: Enhance the simulator with basic experiments to validate the model.
• Impact Analysis: Conduct simulations to examine the effects of various coefficients in the global mass matrix and the influence of drag forces under different conditions.
