An Original Prognostic Method for Single Component of Analog Circuit with Voltage Features

In order to improve the performance of prognostic method for single component of analog circuit, an original prognostic method for single component of analog circuit with voltage features is proposed in this paper. Firstly, a novel formula to calculate fault indicator through Euclidean distance and two test points voltage based slope model is proposed, and according to this formula, a formula to parameter updating through particle filter is get. Secondly, according to these two formulas, the remaining useful life of single-component can be predicted through fault indicator calculation and parameter updating of particle filter proposed in this paper. And finally, the improvement of performance is confirmed in experiments.
