Accurate dynamic modeling is difficult for aerobatic unmanned aerial vehicle flying at its physical limit, due to the model uncertainty caused by unobservable hidden states like airflow and vibrations. Although some progresses have been made, these hidden states are still not properly characterized, rendering system identification problem for aerobatic unmanned aerial vehicle extremely challenging. To address this issue, this paper proposes a novel spectrally normalized adaptive neural identifier for dynamic modeling of aerobatic unmanned aerial vehicle. Specifically, to characterize the model uncertainty, we propose a spectrally normalized adaptive neural network (SNANet) to extract deep features representing the hidden states of the system. Particularly, the proposed SNANet adopts a multi-model adaptive structure, making the model update online quickly and dynamically. Furthermore, the spectral normalization constraint is introduced into the training process to ensure the Lipschitz stability of the SNANet. Consequently, a trajectory tracking control scheme including a SNANet and a sliding mode controller is presented. The modeling effectiveness of the proposed method is verified on a real flight dataset. The results demonstrates that the proposed method has the characteristics of high modeling accuracy, short training time and fast model response speed.
