Abstract

Abstract

Total dynamics of an airship is modeled. The body of an airship was taken as a submerged rigid body with neutral buoyancy, i. e., buoyancy with value equal to that of gravity, and the coupled dynamics between the body with ballonets and ballast was considered. The total dynamics of the airship was firstly derived by Newton-Euler laws and Kirchhoff's equations. Furthermore, by using Hamiltonian and Lagrangian semi-direct product reduction theories, the dynamics was formulated as a Lie-Poisson system, and also an Euler-Poincar system. These two formulations can be exploited for the control design using energy-based methods for Hamiltonian or Lagrangian system.
