发动机故障诊断中工况的模式识别

Pattern Recognization on Working Condition in Diagnosis of Engine

    摘要
  • 摘要: 利用多项式回归的方法获得不同工况下发动机速度随时间变化的数学模型．基于测试工况定义时的模糊性，故在测试中采用模糊模式识别的方法，确定实际的测试工况，以用于测试参数的处理

     

    Abstract: In diagnosis of engine, working conditon is the basis of data analysis, condihon evaluahon and fault diagnosis. Rotating speed signal shows the working condihon.Speed varies with different working condihon. The speed-time model can be obtained by polynomial regression under different working condihon. On the basis of fuzzy pattern recognizaton method, prachcal working condihon can be determined.
