Abstract

The objective of this paper is to design a control law to allow a small fixed-wing Unmanned Aerial Vehicle to extract energy from atmospheric turbulence. From literature data the properties of atmospheric gusts at low altitude are discussed and a single point measurement is proved to be representative of the wind field. The longitudinal flight dynamics of the aircraft is analyzed and the phugoid mode is found to be the main driver of the energy extraction process. A switching controller that places the poles of the phugoid mode depending on the instantaneous variation of energy of the aircraft is designed. Statistical simulations show an increase of energy of the aircraft when this strategy is applied.
