By implementing a local velocity tracking controller, we can model the quadrotor by double integrator dynamics and use the flocking framework. Borrowing ideas from the literature on momentum methods in optimization, we propose a control algorithm and analyze the stability of the closed-loop dynamics under suitable assumptions. We then show in experiments, that by using estimated gradients and Hessians in the presence of noisy measurements of the field strength, reasonable results for convex, log-convex and non-convex scalar fields can be achieved.enConference Paper10.23919/ECC51009.2020.9143867Other
