This chapter deals with descriptor quasi‐linear parameter varying (LPV) systems with unmeasurable decision variables under actuator faults and perturbations. It aims to integrate information provided by the observer into a new state‐feedback design so as to take into account the actuator fault effects in spite of the presence of perturbations. Some preliminary results are mentioned in order to deal with quasi‐LPV systems. The chapter is devoted to describing an adaptive observer for polytopic LPV descriptor systems. It develops the problem statement with quasi‐LPV models, actuator faults and perturbations under unmeasurable scheduling variables. The chapter describes the robust active fault‐tolerant control by state feedback and stability analysis is mainly developed. It examines a new active fault tolerant control (AFTC) methodology for quasi‐LPV descriptor systems, with both …
