Decoupled Control for a High Angle of Attack Missile Based on Differential Geometry Method

The phenomena of nonlinearity and cross-coupling are serious when a missile flights at high angles of attack. At this time, the nonlinearity and coupling caused by high angle of attack itself for the missile must be considered. In this paper, the differential geometry adopted through appended coupling information so that it may eliminate the cross-coupling of the missile. Thus the decoupling control system of missile flight at high angles of attack is designed. At last, the simulation test is done. The simulation results show that the control system can finely maneuver the missile flight at high angles of attack.
