The Research of the Intelligent Fault Diagnosis Optimized by ACA for Marine Diesel Engine
scopus(2010)
摘要
The marine diesel engine has the important function to guarantee the marine security and reliability. It is a strong coupling
relationship’s system with multi-fault attributes. In this paper an advanced method of intelligent fault diagnosis based on
fuzzy neural network (FNN) optimized and trained by ant colony algorithm (ACA) is proposed. The model, structure and parameters
learning of intelligent fault diagnosis based on FNN were described concretely. The weight and the threshold value of this
FNN are optimized and trained by the ant colony optimization algorithm. By simulation that has been carried out to evaluate
the performance of proposed method and to compare with conventional FNN fault diagnosis method for this marine diesel engine’s
combustion system, the results show good quick convergence performance. The knowledge expression and the precision of fault
diagnosis also can be improved effectively. Therefore, this method has the good application prospects in other similar system.
