隐马尔可夫模型(HMM)提供了反映机械系统运行状态及故障信息一种新的信号模型,通过HMM问题的求解,可获得反映机器运行状态特征的信号模型,并应用于机器运行趋势进行预测。
Hidden Markov Model (HMM) provides a new signal model that reflects the operational status and fault information of mechanical system. By solving the HMM problem, a signal model reflecting the operating characteristics of the machine can be obtained and used to predict the trend of machine operation .
