heal.abstract	This paper addresses the issue of studying and improving the reliability and fault tolerance of a given dynamic system using appropriate control design methodologies. The attention is focused on reviewing the two basic approaches to fault tolerance/reliability, namely: the passive and the active approaches. In the passive approach a wide description of system failures is adopted, and a robust control is sought that can tolerate failures as perturbations from a nominal model. On the other hand, in the active approach which is based on an accurate description of failures, through a failure diagnostic unit, the control can be reconfigured on-line. The passive approach is often easier to implement, but can cope with minor failures. So in actual systems the passive solution is used to save time until a more sophisticated active algorithm enters into the system. The theoretical results are illustrated with four application examples.	en
