Danger Model Immune Algorithm (DMIA) is an algorithm based on the danger theory of biological immune system, and it has a good performance in optimization. DMIA is proposed to initialize the weights and biases of wavelet neural network (WNN), the ergodic weights and biases are used for further net-training. The fault diagnosis for marine diesel engine is conducted by using the well-trained wavelet...
Using the traditional PID controller, it can reduce the amount of fuel, decrease the emission of pollutants and can improve the efficiency of the marine diesel engines. Therefore, it is mostly used in the electronic governor of the marine diesel engine's speed control system. However, as the change of sea conditions, the non-linear of the diesel and the change of the load, the parameters of the system...
This paper proposes the wavelet neural network (WNN) based on clonal selection algorithm (CLONALG) for using in fault diagnosis of marine diesel engine. CLONALG initializes the WNN's weights and biases, the ergodic weights and biases are used for further net-training. The fault diagnosis for marine diesel engine is conducted by using the well-trained wavelet network, in order to illustrate the performance...
Based on the modeling method of the co-operation between the characteristic maps and the mathematical equations, a propulsion system simulation model which includes model for large low speed two-stroke diesel engine (MAN B&W 10L90MC) and model for shaft, propeller and ship hull dynamics is proposed. To calculate propeller's characteristic, the regression functions are adopted. The simulation experiments...
