Abstract:This paper addressed the problem of adaptive fuzzy logic systems with backstepping for surface vessels with input dead-zone. The combination of approximation-based adaptive techniques and fuzzy logic systems is used for approximating the nonlinear function from the ship plant. Through backstepping and Lyapunov synthesis, an indirect adaptive fuzzy logic controller is derived for dynamic positioning ships without dead-zone property. In order to improve the control effect, a dead-zone compensator is derived usin… Show more
