This paper develops novel fault tolerant integral sliding mode control allocation schemes for a class of
over-actuated affine nonlinear system. The proposed schemes rely on an existing baseline controller and the
objective is to retain the nominal (fault-free) closed-loop performance in the face of actuator faults/failures
by effectively utilizing actuator redundancy. The online control allocation reroutes the control effort to the
healthy actuators using knowledge of the actuator effectiveness level estimates. One of the proposed schemes
is tested in simulation using a well known high fidelity model of a large civil transport aircraft (B747) from
the literature. Good simulation results show the efficacy of the scheme.
