  Abstract
  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 controller with two time-scale separation is designed to generate the commanded moments, which are then distributed into individual control surfaces by the control allocation module. A dynamic control allocation algorithm is adopted to avoid the shortcomings in static control allocation approaches. Different from most control allocation methods, the actuator dynamics are considered. The flight control design scheme is evaluated by numerical simulation on a nonlinear aircraft model. Simulation results show the validity and good tracking performance of the flight control system.
