Abstract

Global economic infrastructure relies heavily on oil and gas extraction, utilizingresources estimated at 3,336 billion barrels of oil and 625 trillion cubic meters of gas.Offshore extraction, especially using semi-submersible platforms, is crucial for tapping intoundersea reserves in deep waters. These platforms face significant stability challenges fromoceanic forces like waves and wind. Previous research demonstrated the effectiveness offuzzy logic control systems in stabilizing these platforms against such disturbances. Buildingon this, the current study integrates Lyapunov stability functions with fuzzy logic to enhancestability validation and control precision. Simulation results for open-loop and closed-loopresponses demonstrate that the closed-loop fuzzy-Lyapunov control system outperformsconventional fuzzy control, achieving faster convergence, smaller oscillations, and betterdisturbance rejection in surge, sway, and yaw motions.
