| contents | This paper presents a two-layer control framework for Autonomous Underwater Vehicles (AUVs) designed to handle uncertain nonlinear dynamics, including the mass matrix, previously assumed known. Unlike prior studies, this approach makes the controller independent of the robot's configuration and varying environmental conditions. The proposed framework applies across different environmental conditions affecting AUVs. It features a first-layer cooperative estimator and a second-layer decentralized deterministic learning controller. This architecture supports robust operation under diverse underwater scenarios, managing environmental effects like changes in water viscosity and flow, which impact the AUV's effective mass and damping dynamics. The first-layer estimator enables seamless inter-agent communication by sharing crucial system estimates without relying on global information. The second-layer controller uses local feedback to adjust each AUV's trajectory, ensuring accurate formation control and dynamic adaptability. Radial basis function neural networks enable local learning and knowledge storage, allowing AUVs to efficiently reapply learned dynamics after system restarts. Simulations validate the effectiveness of this framework, marking it as a significant advancement in distributed adaptive control systems for AUVs, enhancing operational flexibility and resilience in unpredictable marine environments. |
