Twin ducted fan UAV is a novel aircraft with redundant control effectors and the interactions between actuators and control allocators can not be ignored. In this paper, dynamic control allocation is used to deal with the control allocation problem of Twin ducted fan UAV. First, the actuator rate is penalized in the optimization function of the control allocation based on the quadratic programming method. Second, a post-compensation method is applied to compensate for command increment attenuation. The simulation results show that the dynamic control allocation method with actuator dynamic compensation can prevent the high bandwidth actuator from saturating in advance, and the virtual control command is effectively allocated to actuators with different bandwidths.
