Abstract :
This paper considers modeling and control of a planar kite system with flexible cables used to harvest energy from high-altitude winds. The kite is tethered to flexible cables at its leading and trailing edges. The flexible cables are reeled in and out by ground-based winches. The change in winch inertia and cable stiffness as the cable is reeled in and out is also explicitly modeled. The equations of motion of the flexible kite system are derived using Lagrange´s equation. A specific form of PD control is used control the system as it harvests energy from the wind.
