Abstract :
The design processes and methods of PHM system based on HMM have been investigated. HMM has some advantage in terms of dealing with small sample size and high discerning accuracy. The rationality of sensors set which is based on the hidden Markov model has been evaluated from quantitative point of view. Then the evaluating method of different sensor sets based on HMM has been put forward. At last, the effectiveness of process and method has been validated by using the data of gear case.
