HOVER STABILIZATION OF AN AIRSHIP USING DYNAMIC INVERSION

This paper proposes a new strategy for the hover stabilization of an airship using Dynamic Inversion. We start by introducing a synthetic model of the airship nonlinear dynamics considering forces and moments as input. This model disregards the aerodynamic forces, negligible near hover conditions. Based on the dynamic inversion approach, the model is then inverted so as to obtain the control law. In order to cope with the airship real inputs, a conversion from forces to actuators input is also made. Simulation results illustrate the good performance of the designed controller for the hover control of the Aurora airship.
