【Abstract】 In this paper,an optimal PDM model using the filtering theory is established.A state space model is used to establish the relationship between the condition monitoring information obtained and the residual time of the component,and subsequently the distribution of the residual time given the condition information to data is predicted and updated by the Kalman Filter.On the basis of this,a cost model is formulated to give the recommended‘best’maintenance timing,to minimize the cost per unit time.更多还原
