A Fuzzy Neural Network Control Strategy for Ship Maneuvering Motion

According to the characteristics of ship maneuvering motion control, this paper constructs the membership function and control rules of the input and output language variables of the ship course fuzzy neural network controller, and designs a fuzzy controller. Aiming at the deficiencies of the basic fuzzy controller, a two-stage fuzzy controller with fuzzy PI control and self-adjusting parameters is proposed. When it is applied to the ship heading control system, the system has satisfactory results in terms of immunity and response speed. By establishing the description function of the fuzzy controller, the analysis concludes that the ship course fuzzy control system is stable.
