A three-dimensional fuzzy control method was proposed to solve control problems of ship electric propulsion turbines disturbed by the random sea wave.On the basis of the traditional two-dimensional control method,the space-dimension was added to integrate the feedback information from the multi-detect-device.And by dimension reduction,the illation and defuzzifier of three-dimensional fuzzy controller were dealt as the way of two-dimensional fuzzy controller.The implement strategy of three-dimensional fuzzy control was proposed.The simulation and experimental results show that the three-dimensional fuzzy control method can solve the random disturbance infection of the sea wave effectively.And the method also performs better robustness.The advantages are showed both in dynamic and stabilization performances.The three-dimensional fuzzy controller is useful in improving the turbine control of the ship electric propulsion system.
