In this paper, a Fault Tolerant Control (FTC) strategy based on a bank of virtual sensors is proposed for Linear Parameter Varying (LPV) systems subject to sensor faults, with the novel feature that, instead of hiding the faults as in the classical virtual sensor paradigm, the virtual sensors are used to expand the set of available sensors. An LPV state feedback controller and an LPV state observer are included in the scheme, as well as a parameter that is used by the observer to select which sensors are used among the physical and the virtual ones. An example is used to show the application of the proposed method.
