Abstract

ABSTRACT
A nonlinear ∞ H output feedback controller is proposed and coupled to a PI controller to
regulate an UAV in the presence of aerodynamic force and moment perturbations. The
plant to be controlled is a Quadrotor helicopter described by nonlinear dynamics with
plant uncertainties due to the variations of inertia moments and payload operation. A
robust state estimation is considered under model uncertainties as well as
external/measurement disturbances. Performance issues of the controller are illustrated
in a simulation study made for an UAV prototype.
