The predictive feedback control strategy is used to develop a reconfigurable control system capable of compensating system component faults. The proposed formulation relies on the development of a single step predictor from input-output model that implicitly includes a fault isolation filter. Although no explicit observer is actuallyinvolved in the implementation, this predictor can be understood based due to the fact that an input-output model subsumes an implicit  observer. Exploiting this idea the resulting input-output model is developing from a fault isolation filter. Simulations of a simplelinear system illustrate the properties of the control algorithm in presence of actuator and sensor failures.
