摘要

This thesis targets the problem of fault diagnosis of industrial processes with data-driven approaches. In this context, a class of problems are considered in which the only information about the process is in the form of data and no model is available due to complexity of the process.;Support vector data description is a kernel based method recently proposed in the field of pattern recognition and it is known for its powerful capabilities in nonlinear data classification which can be exploited in fault diagnosis systems.;The purpose of this study is to investigate SVDD applicability as a data-driven method in industrial process fault diagnosis. In this respect, a complete framework for fault diagnosis structure is proposed and studied. The results demonstrate that SVDD is a powerful method in process fault diagnosis.
