THE COMBINATION OF THE BACKSTEPPING METHOD AND OPTIMAL FILTER TO THE FLIGHT STABILITY OF MORPHING AIRCRAFT

Abstract

To ensure the flight stability of morphing aircraft, the paper proposed a
correction system combined with control system. The nominal controller was
designed by the backstepping technique, which was used to provide the basic
flight stability as well as the tracking performance. The correction device was
designed by the receding horizon optimal algorithm based on the command
filter. The retrofit value was calculated to compensate for the nominal controller.
The simulation results show that the flight path angle can track the command
signal regardless of morphing process, and the flight control system satisfies the
requirements of real-time and robustness.
