Featured Application: Large capacity airships (LCA) began the last straight line before the start of their commercial flights during this decade. Many countries are interested in the tremendous potential of these devices and the growing number of applications that could be assigned to them. These include, for example, the transport of logs from areas that are difficult to access, the transport of wind turbine blades to areas that are often remote and far from infrastructure, and the loading and unloading of container ships on the high seas in regions where there are no adequate structures to accommodate these giants of the seas. Additionally, the list goes on. In this paper, we present the stabilization of an unconventional unmanned airship above a loading and unloading area. The study concerns a quad-rotor flying wing airship. This airship is devoted to freight transport. However, during the loading and unloading phases, the airship is very sensitive to squalls. In this context, we present in this paper the dynamic model of the airship, and we propose a strategy for controlling it under the effects of a gust of wind. A feedforward/feedback control law is proposed to stabilize the airship when hovering. As part of the control allocation, the non-linear equations between the control vectors and the response of the airship actuators are highlighted and solved analytically through energy optimization constraints. A comparison with classical numerical algorithms was performed and demonstrated the power and interest of our analytic algorithm. [ABSTRACT FROM AUTHOR] |
