Adaptive robust control of an F-15 aircraft

Abstract

Adaptive Robust Control (ARC) is implemented in conjunction with dynamic inversion to control the response of the F-15 IFCS aircraft. Adaptive Robust Control as described by Yao combines the ability of adaptive control to deal with uncertainty in model parameters with the ability of sliding mode control to deal with exogenous disturbances and other uncertainties. Pilot inputs are translated to roll, pitch, and yaw rate commands. The nonlinear dynamic inversion (DI) control law decouples the system to allow tracking of these commands. ARC is implemented in a control loop outside the DI control loop to provide tracking performance in the face of modeling uncertainties and actuator failures. The control is simulated using a full nonlinear 6-DOF simulation of the F-15 IFCS aircraft.
