The application of control law developed above to the problem of reconflgurable flight control is described. based on the simulation results, the effects of learning rate ( or adaptation gain ) and slide model terms on the control system are discussed. comparing with adaptive control, the control law is helpful to improve system ' s transition response and reduce undesirable oscillations, provides nearly perfect tracking in the case of undetected failure
