Abstract

This work deals with the description of a design procedure for hierarchical Fault Tolerant Control (FTC) of large-scale systems. Following a functional perspective, a procedure for the modular design of the diagnostic and reconfiguration algorithms which run at different levels of the hierarchy is presented. Moreover a hierarchical decision logic algorithm is obtained by means of the theoretical machinery of the supervisor theory of discrete event systems. All the material presented here represents a brief summary of the ideas and results obtained in the context of the European Project IFATIS (proposal number IST-2001-32122).
