This paper presents a new method to evaluate the risk for road networks induced by UAV operations. The hazardous event considered for risk assessment is an accident with damages caused by an UAV falling on a road. Computation models are proposed to evaluate the probability of each event the sequence of which would lead to such an accident. Influences of the type of road as well as the road traffic are taken into account in the models. Simulation results are presented to illustrate risk evaluation by the proposed approach through a case study of a road network of several kilometres. Some metrics are also introduced to analyse the risk in a comprehensive way.

“…As in [8] it is assumed that a loss of control of the UAV corresponds to the failure of the main engine, with a probability of occurrence Pr{loss} = 10 -3 . This assumption is used only for simplicity reason and corresponds to a first order estimate.…”

“…A method for automatically finding a proper landing area for an aircraft in emergency descent is shown in [20], [21], and the ability of a fixed wing aircraft to glide to a designated emergency landing area is presented in [22]. In [23] a study for ground impact fatalities resulting from power failure and subsequent uncontrolled glide is presented. An overview in [24] gives a thorough analysis of a variety of ground impact models.…”

Abstract-The new European legislation expected in 2018 or 2019 will introduce a step-by-step process for conducting risk assessments for unmanned aircraft flight operations. This is a relatively simple approach to a very complex challenge. This work compares this step-by-step process to high fidelity risk modeling, and shows that at least for a series of example flight missions there is reasonable agreement between the two very different methods.

“…Compared with traditional manned airplane and unmanned xed-wing ight vehicles, quadrotor has its unique advantages, such as low cost, small size, and hovering and vertical take-o landing. As a result, quadrotor UAV is applicable in many kinds of elds, e.g., collection of photogrammetry images [1], inspection of railways [2], road detection and tracking [3], management of forest health [4], monitoring power lines [5], and package delivery [6].…”

Robust Tracking Control of a Quadrotor UAV Based on Adaptive Sliding Mode Controller

In this paper, a robust adaptive sliding mode control scheme is developed for attitude and altitude tracking of a quadrotor unmanned aerial vehicle (UAV) system under the simultaneous effect of parametric uncertainties and consistent external disturbance. The underactuated dynamic model of the quadrotor UAV is first built via the Newton–Euler formalism. Considering the nonlinear and strongly coupled characteristics of the quadrotor, the controller is then designed using a sliding mode approach. Meanwhile, additional adaptive laws are proposed to further improve the robustness of the proposed control scheme against the parametric uncertainties of the system. It is proven that the control laws can eliminate the altitude and attitude tracking errors, which are guaranteed to converge to zero asymptotically, even under a strong external disturbance. Finally, numerical simulation and experimental tests are performed, respectively, to verify the effectiveness and robustness of the proposed controller, where its superiority to linear quadratic control and active disturbance rejection control has been demonstrated clearly.
