A discussion is devoted to the design of a robust flight inversion controller for the new generation fighter based on disturbance observer in this paper. According to the time scale separation principle, the flight system is divided into two subsystems,a quick loop and a slow loop. The dynamic inversion controllers are designed for the quick loop and the slow loop. The disturbance observer is used to approximate the disturbance of the fighter and to on-line compensate the model inversion error. Finally, the simulation results demonstrate the availabilityof the designed robust flight controller.
