“…A tethered towed vehicle (TTV) is a type of special application vehicle that is connected to the main aircraft by a cable. It is used in various applications, including autonomous aerial refueling (AAR) [1], towed aerial launches, towed UAV aerial recovery [2], and tethered towed targets. The strong connection restrictions of flexible cables make it difficult for a TTV to fly steadily in complex flow fields.…”

Due to wind disturbances and various uncertainties, maintaining the stability of a tethered towed flight system is extremely challenging. This study proposes an anti-disturbance cooperative control scheme for a towed vehicle equipped with a flexible canopy. The proposed scheme effectively mitigates the impact of time-varying external disturbances, model uncertainties, and state and output constraints. Unlike existing studies, this paper addresses the unknown time-varying aerodynamic parameters of a tethered towed vehicle for the first time. Additionally, by integrating an adaptive neural network with a disturbance observer, a composite estimator is developed to tackle the effects of model uncertainties and time-varying disturbances. The state-constrained problem is addressed using an anti-saturation method based on auxiliary systems. The uniform boundedness of the controller signal is proven using the Lyapunov method. Numerical simulations validate the effectiveness of the proposed method in terms of disturbance rejection.

“…In terms of economics, repeated use of UAVs is the most cost-effective approach. Therefore, automatic recovery [1][2][3] is the key to developing UAVs. Compared to fixed-rotor UAVs, multi-rotor UAVs have a simpler structure, convenient maintenance and strong flexibility, but their cruising power is significantly reduced.…”

This study proposes an aerial recovery technology that can complete aerial recovery for target unmanned aerial vehicles (UAVs) by a platform UAV to overcome the limitation of ground recovery for multirotor UAVs. To ensure the safety of automatic aerial recovery, more requirements are made for the stability of multi-rotor UAVs. This study proposes a back-stepping trajectory tracking controller for feedforward compensation of uncertain disturbances. The results of the simulation show that the controller can effectively prevent external disturbance and meet requirements for the desired trajectory tracking. Furthermore, based on a you only look once (YOLO) network, this study designs a real-time image recognition and positioning system, which can achieve real-time positioning for platform UAV by the target UAV with an image-processing rate of 8 frames per second (FPS). With the main objective of safety, this study designs an automatic recovery guiding system for target UAVs using a fuzzy controller. The target UAVs can automatically realize a soft landing on the platform UAV effect of the guiding system. Finally, this study conducts dynamic recovery tests inflight and verifies the feasibility of automatic aerial recovery technology for multi-rotor UAVs.
