“…Both problems have been preliminarily studied in the literature, for instance, [14] and [15] present a control scheme which takes into account the movement of the arm of aerial manipulators while [16] is focused on the controller of multirotors working close to ground surfaces. External wrench observers [17] have been used to estimate unknown forces and torques acting on the multirotor, and design controllers for the aerial robot [18]. These observers could be used to estimate these aerodynamic effects, although the when the multirotor approaches the surfaces there are large gradients in the generated forces, and wrench observers are not well suited for estimating fast varying forces.…”

This paper presents the design, modelling and control of a multirotor for inspection of bridges with full contact. The paper analyzes the aerodynamic ceiling effect when the aerial robot approaches the bridge surface from below, including its aerodynamic characterization using Computational Fluid Dynamics (CFD). The proposed multirotor design takes the modelled aerodynamic effects into account, improving the performance of the aerial platform in terms of the stability and position accuracy during the inspection. Nonlinear attitude and position controllers to manage the aerodynamic effects are derived and tested. Last, outdoor experiments in a real bridge inspection task have been used to validate the system, as well as, the controller and the aerodynamic characterization. The experiments carried out also include a complete autonomous mission of the aerial platform during a structural assessment application.

We introduce a new kind of aerial manipulator based on multirotors. This device exploits the rarely used yaw movement which characterizes these aircrafts in order to generate and transmit forces and displacements trough a serial-chain of rigid links and other drones, as if the whole system was a flying robot arm with UAVS as rotational joints. Also we provide comparisons with the existing technologies and a condensed review concerning them. Finally, this paper proposes many open problems in order to develop the final system. Due to the scientific and social impact of this new approach, we provide some application examples.

“…In [19], the design of two nonlinear controllers to stabilize an aerial vehicle characterized with quaternions and their axis-angle depiction is studied. Also, [20] introduces a PBC for a vertical take-off and landing (VToL) vehicle. An estimator of unmodelled dynamics and external wrench acting on the UAV and based on the momentum of the system is used to compensate such disturbance effects.…”

Energy-Based Control and LMI-Based Control for a Quadrotor Transporting a Payload

et al. 2019

This paper presents the control of a quadrotor with a cable-suspended payload. The proposed control structure is a hierarchical scheme consisting of an energy-based control (EBC) to stabilize the vehicle translational dynamics and to attenuate the payload oscillation, together with a nonlinear state feedback controller based on an linear matrix inequality (LMI) to control the quadrotor rotational dynamics. The payload swing control is based on an energy approach and the passivity properties of the system’s translational dynamics. The main advantage of the proposed EBC strategy is that it does not require excessive computations and complex partial differential equations (PDEs) for implementing the control algorithm. We present a new methodology for using an LMI to synthesize the controller gains for Lipschitz nonlinear systems with larger Lipschitz constants than other classical techniques based on LMIs. This theoretical approach is applied to the quadrotor rotational dynamics. Stability proofs based on the Lyapunov theory for the controller design are presented. The designed control scheme allows for the stabilization of the system in all its states for the three-dimensional case. Numerical simulations demonstrating the effectiveness of the controller are provided.
