Adaptive Fuzzy Consensus Control for Three-Buoy Platforms

This paper addresses an adaptive fuzzy consensus control problem for three-buoy offshore floating platforms. Firstly, the three-buoy floating platform is analyzed in three-dimensional space, and a control system model is established. In order to achieve stability for the floating platform, the unknown nonlinear dynamics of the established system are approximated by fuzzy systems, which yield an adaptive fuzzy consensus controller by employing a consensus strategy. The stability of the closed-loop system and the convergence of the relative displacements among the three buoys are also analyzed. Simulation results show the effectiveness of the proposed control method.
