The tethered system, which composed with mother ship and satellite connected with tether, is an example of recent satellite. In the analysis and modeling of tether, large deformation and displacement must be considered. Absolute Nodal Coordinate Formulation can describe the motion of tether. In the modeling method, internal damping and fluid resistance is not considered, and identification for such parameter is still problem to be solved. In this study, the effect of internal damping and fluid resistance based on strain energy and drag equation are formulated while considering parameter identification method. In order to verify the modeling method, an example of swing up control will be performed in simulation and experiment.
