A large volume of literature exists on fault detection and isolation for industrial processes. In a general view, these various methods may be divided into process model based and process history based fault diagnosis. In both classes, there has been a recent focus on extracting the temporal information corresponding to process transitions between various operating modes. In this context, Hidden Markov Models (HMMs) have been introduced and applied for process monitoring and diagnosis purposes. The main objective of this thesis is to develop novel HMM based approaches to diagnose various operating modes of a process. Mode in this thesis refers to process operational status such as normal operating condition or fault.
