| 摘 要： | 提出了一种基于分形的航天器故障预报新方法，并给出具体预报公式。由于故障发生前都蕴含前兆因子，这些因子可导致测量信号分形维数的变化，根据这些变化可进行故障预报，该方法理论明确，参数简单，克服了传统故障预报方法易丢失故障信息的缺点。

| Abstract: | A new aircraft fault prediction method based on fractal dimension was proposed and the prediction formula was given Before the fault happened, there will be some symptoms that can induce the change of fractal dimension of measurement signal, then the prediction was carried out according to this change The theory of this method is clear and its parameters is simple Moreover, this method overcomes the shortcomings of the traditional prediction method and has an important practical meaning to understand and use the fractal dimension change of the symptoms to carry through aircraft fault prediction |
