| Popis: | This paper proposes reversed pumping as a strategy to keep tethered kites airborne in a wind-free condition without any on-board propulsion. In the context of kite power, it is shown to be a necessary addition to a rotational start-up scheme. The enhanced scheme ultimately allows for injection into power harvesting orbits at high altitude, in case no wind is present near ground level. The need for reversed pumping is advocated with scaling laws, and is demonstrated in simulation by solving a proposed open-loop periodic optimal control problem. The obtained periodic orbits can be used as reference for feedback control. ispartof: pages:2527-2532 ispartof: 2012 American Control Conference pages:2527-2532 ispartof: American Control Conference location:Montréal date:27 Jun - 29 Jun 2012 status: published |
