Fault Diagnosis of Diesel Engine Based on Gravitational Search RBF Neural Network

In order to solve the optimization of the parameters of RBF neural network to improve the accuracy of fault diagnosis of diesel engine,an intelligent fault diagnosis method based on the combination of gravitational search algorithm and RBF neural network is proposed.At first,the subtractive clustering algorithm is used to determine the number of hidden layer units,then the improved gravitational search algorithm is adopted to optimize the parameters of RBF neural net-work.UCI testing data sets are used to check the classification accuracy of the proposed method, and the proposed method is applied to fault diagnosis of diesel engine.Simulation results show that the proposed method is effective in classification and diagnosis of the faults of diesel engine.
