Stability and Control Analysis Based on Airship Dynamic Modeling
This paper presents a 6DOF(Degree of Freedom) nonlinear dynamic model for a special kind of airship, which is based on the body axes coordinate system with the origin at the center of the volume. Firstly, the related physical principles of airship are comprehensively reviewed. Then, the nonlinear dynamic model is linearized based on linear perturbation theory, and divided into longitudinal and lateral equations. The stability, mode, controllability and turbulence motion of the airship are studied through the presented model. Simulation results demonstrate that the lateral and longitudinal motions of the airship are static stable and controllable, and the longitudinal and lateral motions can be divided into three modes according to the different eigenvalues respectively.
