摘要
主要介绍了小波变换的原理和应用,着重研究了基于连续小波变换极值点的方法在传感器故障诊断中的应用。最后,利用Matlab软件中的Simulink工具箱建立传感器系统的故障模型进行仿真研究,证明该方法的可行性。
The thesis mainly introduces the theory and application of Wavelet Transform. We mostly study the fault diagnose of sensor based on the singularity of the Continuous Wavelet Transformation. In the end, the factual example of fault model of sensor system is simulated with simulink toolbox of the software of Matlab, and the resuh testifies the feasibility of the way above.
