摘要：

In this paper, the design of the adaptive fuzzy observer of the ship's Rudder Roll Damping (RRD) system is proposed. The fuzzy T-S models of the RRD system with the nonlinear hydrodynamic coefficients are established. Using the Lyapunov stability method and the adaptive theory, the asymptotic stability conditions of the observer error system are obtained. The design of the adaptive fuzzy observer is put forward on the basis of the above conditions. The simulation results show that the adaptive fuzzy observer is suitable for the RRD system. Compared with the common fuzzy observer, the adaptive fuzzy observer is suitable for the ship with both low and high speed, and can get good observation results.
