摘要
分析了摆式列车倾摆控制系统的可能故障 ;提出由信号的小波变换的奇异点在多尺度上的综合表现是否有突变来检测倾摆控制系统的执行器和传感器故障并对陀螺仪故障诊断进行了计算机仿真分析。结果表明 。
The probable failure of tilting mechanism control system is analyzed. Failures on actuator and sensor of tilting control system are detected by checking whether there is a sudden change on the singularities in the wavelet transform of signal under the condition of multidimensional comprehensive behaviors, and the simulation of the gyroscope failure result shows that the detecting method proposed in this paper is fairly effective.
