An adaptive robust control technique is developed for an uncertain riser-vessel system in a three-dimensional space. A projection mapping technique and a hyperbolic tangent function are utilized to construct novel adaptive robust controllers based on dynamically updated adaptive laws. The stability of the closed-loop system is analyzed using Lyapunov's method.
In this study, an adaptive robust control technique for an uncertain riser-vessel system in a three-dimensional space is developed. A projection mapping technique and a hyperbolic tangent function are exploited to construct novel adaptive robust controllers based on adaptive laws dynamically updated online to restrain the vibration, tackle parametric uncertainties, compensate for the unknown upper bound of disturbances, and ensure robustness of the coupled system. Lyapunov's method is adopted to analyze and demonstrate the bounded stability of the closed-loop system. Simulation results are provided to validate the feasibility and effectiveness of the proposed approach.
