“…Moreover, if a dynamical system cannot be globally asymptotically stabilized through continuous feedback, it cannot be robustly stabilized by discontinuous feedback either, as shown in Mayhew and Teel [2011]. Overcoming these limitations is particularly important for multi-rotor aerial vehicles due to their popularity and the wide range of applications in which they are used, such as surveillance, tracking, search and rescue, infrastructure inspection, agriculture and disaster mitigation (see e.g Fink et al [2011], Mellinger et al [2012], Jiang and Kumar [2013], Augugliaro et al [2013], Lupashin et al [2014], Floreano and Wood [2015] and Liang et al [2018]). In this paper, we present a hybrid controller that not only provides global exponential stability, but also confers a quantifiable robustness margin to perturbations.…”
