Information Entropy Based Diagnostics of Mechanical Systems
Original language description
The article deals with the problem of fault diagnosis of mechanical systems. The traditional approach is based on the evaluation of the change of physical parameters of the system based on identification. Such an approach often fails due to various stochastic excitations of the system. This paper describes a different approach based on computational information entropy. Information entropy does not lead directly to the identification of physical parameters, but it can distinguish between the behaviour of the original system and the system with changed physical parameters due to some failure. Another advantage of information entropy is that it provides a single value for detecting changes in the physical parameters of a mechanical system. This approach is particularly advantageous for OMA (operational modal analysis) of elastic mechanical systems where the identification encounters the problem of knowing the excitation.
