Energy Tank-Based Wrench/Impedance Control of a Fully-Actuated Hexarotor: A Geometric Port-Hamiltonian Approach

Abstract: In this work, we show how the interactive behavior of an aerial robot can be modeled and controlled effectively and elegantly in the port-Hamiltonian framework. We present an observer-based wrench/impedance controller for a fullyactuated hexarotor. The analysis and control are performed in a geometrically consistent manner on the configuration manifold of the special Euclidean group SE(3) such that the UAV's nonlinear geometric structure is exploited. The controller uses a wrench observer to estimate the inter… Show more
