7.1 Introduction

Fault detection implies a two-valued outcome depending upon the normal or abnormal operating characteristics of a system [1]. Fault diagnosis is the process that actually decides the cause, nature, and location of a fault. Incipient fault diagnosis may even be the preemptive process to minimize damage due to faults. To make a fault diagnosis scheme incipient, it requires monitoring the system at every instant. The most logical way to implement this is to compare the system outputs with set reference values. This could be based on three possible ways: (1) signal, (2) knowledge, and (3) model. In a signal-based ...
