Surveillance et diagnostic des systèmes

Have a global vision of what are monitoring and diagnostic

Know different monitoring and diagnostic methods and their fields of application

Identify the main functions involved in monitoring and diagnostic

Course work

• Degradation and faults in electromechanical systems, static converters, passive components (capacitors and inductors), cables and insulators,
• Introduction to diagnosis, supervision and health monitoring, principles and example of existing protections and monitoring solution
• Introduction to dependability
• Classification of diagnosis approaches: model and signal based diagnosis methods, examples of degradation monitoring and fault detections
• Several examples of condition monitoring and diagnosis methods
• Design of experiments as a degradation and lifespan modelling method

Lab project on diagnosis and supervision

1. Illustration of signal-based methods:

-          detection of mechanical unbalance through spectral analysis. (Fast Fourier Transform, Concordia transform).

-          detection of driver drowsiness using time-frequency approaches (Short time Fourier transform, Student T-test, ROC curves).

2. Experimental nonlinear lifespan modeling of electrical wire insulation samples (Design of Experiments, Analysis of Variance)
