Abstract
A fault-tolerant control scheme including integral sliding mode, control allocation and parameter identification is introduced to deal with faults together with uncertainties and saturation. The Lyapunov stability is guaranteed by stability conditions respectively for uncertainties and saturations. Faults are tolerated by control allocation scheme based on the efficiency parameters, which call for a special requirement of parameter identification. The method is applied to a six-wheel spacecraft and simulation shows its effectiveness.
