Robustness issues in fault-tolerant control

Provides a perspective on the state of the art in robust approaches to fault-tolerant control and gives some indication of ways in which the research may best proceed. Key themes are the individual robustness properties of fault detection, fault isolation and controllers used as elements in a fault-tolerant system. Comparisons between active and passive approaches are made and emphasis is placed on the overall robustness properties of the fault-tolerant control system
