Abstract

An integrated integral sliding mode fault tolerant control scheme is proposed for the linear parameter varying (LPV) plants in the output feedback framework. To estimate the unavailable plant states, an unknown input LPV observer is employed. The feedback and observer gains are designed using linear matrix inequalities approach to ensure closed-loop stability nominally and in the situation of actuator faults/failures. An integral sliding modes approach in the LPV framework together with control allocation maintains the nominal performance in the presence of permissible set of actuator faults/failures. A rigorous closed-loop stability analysis is carried out and to show the feasibility of the proposed approach it is tested in simulations on the non-linear plant of a passenger aircraft.
