Introduction
Fault detection is the process of detecting failures, also known as faults, in a dynamical system. It is an important area for systems that are supposed to operate without human supervision. There are many ways of detecting failures. The simplest is using boolean logic to check against fixed thresholds. For example, you might check an automobile’s speed against a speed limit. Other methods include fuzzy logic, parameter estimation, expert systems, statistical analysis, and parity space methods. In this ...
