Research on sailboat control method based on Sugeno fuzzy model

A fuzzy control method based on Sugeno fuzzy model is proposed for the nonlinear and time-variant (navigation) system of sailboats. Sailing rules obtained from excellent helmsmen are included in a knowledge base to (control) the sailboat correctly in various conditions. The controller uses Sugeno fuzzy model to divide the nonlinear control system into several local linear models, based on which several local linear controllers are constructed. The global control output is obtained by combining all the local linear controllers′ output. Simulation results show that this method can efficiently implement autonomous navigation of sailboats.
