Moving Target Landing of a Quadrotor Using Robust Optimal Guaranteed Cost Control

Dear Editor, This letter proposes a robust control strategy for the autonomous landing of quadrotor on moving target. Specifically, force command that consists cascade dynamics estimator and an optimal guaranteed cost law is exploited position-loop tracking. Then, orientation constraint torque employed attitude-loop tracking such refrains from flipping during operation. Stability analysis indicates overall closed-loop system asymptotically stable. Finally, flight experiments validate access theoretical results.
