This article develops a fault-tolerant control strategy for a multi-propeller aerostat based on sliding mode control allocation approach. And the loss of effectiveness of propeller faults and the wind disturbance is considered in the system. The proposed control approach consists of two modules: the upper-level virtual control part, which is developed to enable the closed loop system asymptotically stable; the lower-level control allocation part, which can accommodate the propeller faults, and redistribute the virtual control vector to the available propellers. Stability analysis indicates that the aerostat plant is globally asymptotically stable. The validity of the developed fault tolerant control strategy is proved through simulation results based on a simplified multi-propeller aerostat with propeller faults.
