An overview on nonlinear reconfigurable flight control approaches that have been demonstrated in flight-test or highfidelity simulation is presented.Various approaches for reconfigurable flight control systems are considered,including nonlinear dynamic inversion,parameter identification and neural network technologies,backstepping and model predictive control approaches.The recent research work,flight tests,and potential strength and weakness of each approach are discussed objectively in order to give readers and researchers some reference.Finally,possible future directions and open problems in this area are addressed.
