Resumen:

This chapter presents a strategy for control reconfiguration based upon time delay knowledge as well as local fault effects within a distributed system environment considering the magnetic levitation challenge. These two approaches are followed, in cascade mode, structural reconfiguration, and control reconfiguration. Although there is no formal verification to follow this sequence, it has been adopted since structural reconfiguration provides settle conditions for control reconfiguration. Time delays are measurable and bounded according to a real-time scheduling algorithm. In this case the scheduling algorithm is the well known earliest deadline first (EDF) algorithm. The core of this algorithm is to perform online reconfiguration based upon a review of the proposed plan. The local time delay bounding allows the design of a control law capable to cope with new conditions. © 2007 Copyright © 2007 Elsevier Ltd All rights reserved.
