PILOT-VEHICLE SEMI-PHYSICAL SIMULATION STUDY OF DECOUPLING CONTROL FOR AIRCRAFT TF/TA PENETRATION

The effect of turbulent disturbance on the behavior of decoupling control in case of an aircraft penetrating at low level by using TF/TA technologies and control and its riding quality of the pilot are studied by pilot-vehicle semi-physical simulation technique. At the same time, the tracking behavior of nonlinear decoupling system on the real-time control command of the pilot is verified,too. The simulation results show that some nonlinear cross couple between longitudinal and lateral movements of the aircraft can be eliminated by the decoupling control law, and it offers better decoupling control and riding quality of the pilot. The work load of the pilot could be reduced greatly, and the result of research theory is verified, too.
