A new flight control system design scheme is presented for attitude tracking problem, which integrates hierarchy-structured nonlinear dynamic inversion (NDI) and dynamic control allocation techniques. The hierarchy-structured NDI with two time-scales separation is designed to generate the required aerodynamic moments for given attitude angles command. To avoid the shortcomings in static control allocation approaches, a dynamic control allocation algorithm is adopted to distribute the moments into individual control surfaces. Different from most control allocation methods, the actuator dynamics are considered. The flight control design scheme is evaluated by numerical simulation on a nonlinear six degree-of-freedom aircraft model. Simulation results show the validity and good tracking performance of the flight control system.
