In this paper, a fault tolerant control strategy, which combines a fault detection and identification (FDI) method based on an invariant-set approach with controller reconfiguration based on the use of a virtual sensor, is implemented on a magnetic levitation (MAGLEV) system. The MAGLEV system includes two sensors which, together with a nominal observer-based feedback controller with integral action,...
The control of flexible mechanical systems has been extensively studied in a variety of fields. For mechanical systems with collocated sensors and actuators, the use of symmetric controllers is known to be effective. The symmetric controller guarantees the robust stability of the closed-loop system irrespective of the system parameters by virtue of the structure of the dynamical equation having positive...
