Application of Intelligence Controller for Marine Main Engine System

A type of intelligence PID controller based on BP neural network is proposed. That the robust intelligence PID controller contains three-layer fuzzy neural network is simple in structure and steady in work. The PID parameters can be self-adjusted according to the system model and can be automatically tuned via neural networks weights. This controller is used in marine engine propulsion system to control the engine speed. The simulating results indicated that the system possesses fast response speed and good performance of anti-disturbance better than the traditional PID controller, and that the intelligence PID controller can obtain better result and robustness than the traditional PID controller. The marine engine speed can be stabilized well by the intelligence PID controller. Now, the intelligence PID controller has been successfully used in marine engine propulsion system simulator in Dalian Maritime University and a satisfactory training is provided.
