A probabilistic robust control method for a small UAV with bounded uncertainty

This paper proposes a probabilistic robust control approach for a small unmanned aerial vehicle (UAV) in longitudinal flight. In the proposed method, the stochastic behavior of uncertainty parameters is considered in solving a high-performance robust controller of UAV. Compared to deterministic robust control, this solution has two advantages: (a) the controller obtained by the proposed method has fixed order; (b) it is less-conservative and more reasonable for controlling flight control systems with bounded uncertainty. Simulation results for an UAV in longitudinal motion are given to show the effectiveness of the proposed approach.
