Fault reconstruction using a LPV sliding mode observer for a class of LPV systems

► This paper has proposed a new LPV based sliding mode observer scheme for fault reconstruction. ► The virtual actuator fault reconstructions are based on the 'equivalent output error injection signals' of the observer. ► For sensor faults, the observer design has involved re-formulating the problem into an actuator fault reconstruction framework. ► This allows the LPV observer synthesis approach for the actuator faults to be applied directly.
