Abstract
This paper illustrates simulation of retrieval of a tethered satellite system. The simulation takes the mass and flexibility of the tether into consideration, and its model is called a flexible model. In the control design, the mass and flexibility of the tether are neglected, and the controlled system is expressed by a bilinear state equation, which is called a simple model. We compare simulation results of the flexible model and the simple model under nonlinear receding horizon control, which is designed for the simple model, and inspect the influence of the tether-flexibility.
