control reconfiguration concerns the problem of finding a new control configuration and new controller parameters after faults have brought the nominal controller out of operation. This paper develops the idea of the generalised virtual actuator, which is a reconfiguration block to be inserted between the faulty plant and the nominal controller. General properties of the reconfigured closed-loop system like the separation principle for the generalised virtual actuator are proved and guidelines are given for the choice of the free parameters. The new reconfiguration scheme includes several ideas that have been recently developed for specific situations and makes it possible to use a uniform reconfiguration algorithm in all these situations. The results are illustrated by presenting a solution to the COSY benchmark problem. Copyright (c) 2006 IFAC.
This paper considers the data communication of remote diagnosis, which is decomposed into an on-board and an off-board diagnostic task. A new method to reduce the data traffic from the on-board component to the off-bo...

This paper proposes a self-organising networked controller for disturbance attenuation in multi-agent systems. A disturbance affecting a single agent has some effect on all neighbouring agents through the communicatio...

Networked controllers are used to synchronise autonomous agents by driving the agent states towards a common trajectory. This paper analyses the command-following behaviour of leader-follower systems in dependence upo...

Geometric fault detection and isolation filters are known for having excellent fault isolation, fault reconstruction and sensitivity properties under small modeling uncertainty and noise. However they are assumed to b...

Due to the characteristic of no blanking time, dual buck topology is attractive in high precision applications and the bias current is injected to eliminate zero crossing distortion. However, with the extending of bus...

This paper presents the model-based diagnosis in the framework of discrete-event systems. Timed automata are used as a discrete-event representation which is suitable for consistency-based diagnosis. The diagnostic st...

Any technical system is liable to the occurrence of faults. A major fault in the plant like the complete loss of an actuator or sensor breaks the control loop and renders the system in-operational, unless the control ...
