โœฆ Synopsis

To diagnose faults in engineering structures in the situations where the excitation signals are unavailable or inaccessible, response-only data, transmissibility function, are utilised to train neural networks. The technique is verified with two examples based on two different structural systems. The neural network classifiers clearly deliver the diagnostic indications of the faults introduced into the structural systems, which suggests that the transmissibility function is a sensible response-only data source for structural fault diagnosis.

This article presents a model-based fault diagnosis method to detect and isolate faults in the robot arm control system. The proposed algorithm is composed functionally of three main parts: parameter estimation, fault detection, and isolation. When a change in the system occurs, the errors between t
