| Abstract: | A fault prognosis method for system based on dynamic damages of multi-components induced by time stress is studied.A damage evolution model for the component of electronic system is put forward by analyzing the damage accumulation mechanism.The fault prognosis model for electronic system is researched based on the hidden Markov model(HMM) of multi-components,and the process and algorithm of the method are introduced in detail.Finally,the validity of the fault prognosis method is proved by an experimental study of the switching circuit system. |
