Along with the increase of the level of complexity, integration and intelligence of missile weapon system, prognostics and health management technology (PHM) has gotten more and more attention and application. The technology has become the key technology of increasing the reliability, testability, maintainability and supportability of missile weapon system. Doubtless, the higher requirements are put...
In this paper, we focus on the prediction method of building energy consumption time series. The building energy consumption data can be regarded as a time series, which is usually nonlinear and non-stationary. Traditional time series analysis model has lower prediction accuracy. Then the machine learning method, especially support vector regression algorithm always has better performance to deal...
Considering the influence of the weather conditions to incoming solar radiation, this paper analyzes the relation among the sunshine, weather types, and radiation parameters, then divides them into 4 types of common weather (perfectly clear, generally clear, generally cloudy and perfectly cloudy). Diffuse model, diffuse proportion, and transitivity correspond to the different weather types. Taking...
In this paper, an agile fault injection method by means of discretional fault mode is introduced, in order to go over the localization of the conventional fault injection method based on the hardware, and to offer a new means that is used to validate the testability indexes of PHM system. After describing the basic principle of such method, this paper discusses universal elements and groupware modeling,...
The circuit fault injection based on EDA simulation is one of the efficient methods of testability analysis. In order to implement fault simulation, the first step is to establish the models that reflect the function or fault modes appropriately. Considering the various components of number systems in PHM system, although the prevalent software contains parts libraries, the symbols in the libraries...
