Abstract

In order to perform condition monitoring and fault diagnosis for large-scale and complex and key mechanical equipment effectively, hybrid intelligent fault diagnosis and prognosis technique by synthesizing and utilizing multiple artificial intelligent techniques and advanced signal processing methods, has been given high regard and studied widely by inland and overseas researchers. Based on investigating a good deal of relevant literature, the extensive concept of the hybrid intelligent fault diagnosis and prognosis technique is introduced, the inland and overseas state-of-the art is reviewed in this paper, and the problems existing in present studies are also analyzed and pointed out. Finally, aiming at the state-of-the art and existing problems, the development trends of the hybrid intelligent fault diagnosis and prognosis technique are discussed in the end of the paper.
