Multi-UAV formation maneuvering control based on Q-Learning fuzzy controller
Pang Rui · 2010
On the basis of the relative motion relations of the formation flight, UAV longitudinal and lateral fuzzy controllers are designed to solve the multi-UAV formation control problem. The relative positions between adjacent UAVs are controlled to meet the desired commands and performance requirements. Q-Learning method, which is one kind of reinforcement learning, is used to tune the corresponding parameters in output membership functions of fuzzy controller. This auto-tuning avoids the complexity of manual tuning with expert experience and eliminates the steady state errors. Also, different conditions including coordinative turning, tense-loose shape changing, shape sequence changing and collision avoiding are simulated with the formation control methodology, which is comprised of centralized decision and decentralized control. The results prove the correctness of control method and formation control strategy under the circumstances of different formation maneuvering demands.
