The complexity of modern systems is increasing rapidly and the dominating relationships
among system variables have become highly non-linear. This results in difficulty in the …

A self-organizing map (SOM) based methodology is proposed for fault detection and
diagnosis of processes with nonlinear and non-Gaussian features. The SOM is trained to …

This paper presents an approach for the detection of the degradation onset and the
identification of the degradation state of industrial components with inhomogeneous …

The development of data-driven models for the identification of the degradation state of
industrial components is challenged by several issues, such as the unavailability of large …

Abstract Insulated Gate Bipolar Transistors (IGBTs) are one of the most used power
semiconductor devices for energy conversion applications, due to their high performance. In …

In this paper, the use of Self-Organizing Maps (SOM) for fault diagnostics is proposed. The
method is tested with an artificial case study representing three start-up faulty behaviors of …

Modern industrial processes are systems with a high degree of complexity. These systems
comprise of a large number of components functioning in harmony to produce high quality …
