Condition Monitoring and Fault Tolerant Control

Condition Monitoring (also referred to as Fault Detection) covers a wide range of techniques for detecting and also isolating faults and failures in plant. Some methods rely on plant models (either linear or nonlinear (e.g. neural network model)) whereas others use heuristic methods. Fault Tolerant Control is the group of control techniques that allow some form of control to be maintained in the presence of plant faults, this includes reconfigurable control.
