H∞ state feedback control for UAV maneuver trajectory tracking

In this paper a trajectory tracking system for UAV is studied. The system consists of a flight control system and a guidance law. In inner loop, robust H_∞ control theory is used to design the flight control system. In outer loop, the navigation control commands are produced by the deviation of the real position data of UAV and the preset flight path. The attitude commands are calculated from navigation control commands and are fed into the inner loop as input signals. Simulation results are presented to illustrate the performance of the trajectory tracking control system. The results show the effectiveness and practicability of the control method.
