A Review on Electromechanical Systems Prognostics

As an important technical foundation of Intelligent Maintenance Systems(IMS) and Prognostics Health Management(PHM),prognostics has been paid more and more attentions in recent years.This review article firstly synthesizes these individual pieces of information about electromechanical system prognostics,and then discusses its development situation from a two-dimensional angle of view—objects and methods,while identifying their merits and drawbacks.The relevant objects and available fault prognosis methods are classified into four and five categories,respectively.Finally,some open problems in this field are also discussed,together with possible advanced research directions.
