Research on Cooperative Planning Technique of Gliding Trajectory for Multi-aircraft

In order to make multi-aircraft cooperating with each other and reaching the specified target area at the same time, the gliding trajectory cooperating planning is studied. The trajectory planning model is established. For a single aircraft, online trajectory generation based on the height vs velocity ( H-V) profile is achieved, and a feedback linearization tracking guidance law is designed. For multi-aircraft, a multi-aircraft trajectory planning strategy based on time coordination is designed. Multi-aircraft trajectory cooperating planning under two different operational backgrounds is simulated. Simulation results show that the algorithm can achieve multi-aircraft trajectory cooperating planning, and multi-aircraft can reach the target area at the same time.
