An optimization study has been conducted and the corresponding con-trol strategy developed for the lighter-than-air airborne wind energy system. The linchpin of the system is an airborne module in the form of a buoyant, rotating cyl-inder, whose rotation in a wind stream induces the Magnus effect-based aerody-namic lift, thereby facilitating traction power generation. The optimization is aimed at maximizing the average power produced at the ground based generator during a continuously repeatable operating cycle. This chapter provides a recap of the optimization methodology, results, and their physical interpretation, and builds on this foundation to develop control strategies aimed at approaching the optimi-zation results. Comparative analysis of the two proposed control strategies and the optimization results shows that the simpler and more robust strategy can approach the performance of the more sensitive strategy that closely matches the optimiza-tion results.
