Adaptive Tracking Control of an Autonomous Underwater Vehicle

International Journal of Automation and computing 2014年第3期11卷 299-307页

作者： basant Kumar Sahu Bidyadhar Subudhi Centre for Industrial Electronics and Robotics Department of Electrical Engineering National Institute of Technology

This paper presents the trajectory tracking control of an autonomous underwater vehicle(AUV). To cope with parametric uncertainties owing to the hydrodynamic effect, an adaptive control law is developed for the AUV to track the desired trajectory. This desired state-dependent regressor matrix-based controller provides consistent results under hydrodynamic parametric *** of the developed controller is verified using the Lyapunov s direct method. Numerical simulations are carried out to study the efficacy of the proposed adaptive controller.

Stability Analysis of an Underactuated Autonomous Underwater Vehicle Using Extended-Routh's Stability Method

引用

International Journal of Automation and computing 2018年第3期15卷 299-309页

作者： basant Kumar Sahu Bidyadhar Subudhi Madan Mohan Gupta Department of Electrical Engineering National Institute of Science and TechnologyBerhampur Department of Electrical Engineering National Institute of TechnologyRourkela Intelligent Systems Research Laboratory College of Engineering University of Saskatchewan

In this paper, a new approach to stability analysis of nonlinear dynamics of an underactuated autonomous underwater vehicle（AUV） is presented. AUV is a highly nonlinear robotic system whose dynamic model includes coupled terms due to the hydrodynamic damping factors. It is difficult to analyze the stability of a nonlinear dynamical system through Routh＇s stability approach because it contains nonlinear dynamic parameters owing to hydrodynamic damping coefficients. It is also difficult to analyze the stability of AUVs using Lyapunov＇s criterion and LaSalle＇s invariance principle. In this paper, we proposed the extended-Routh＇s stability approach to verify the stability of such nonlinear dynamic systems. This extended-Routh＇s stability approach is much easier as compared to the other existing methods. Numerical simulations are presented to demonstrate the efficacy of the proposed stability verification of the nonlinear dynamic systems, e.g., an AUV system dynamics.
