Modeling orbital tether system deployment with limitations on the deployment speed

Abstract

The problem of modeling the operation of special equipment intended for modeling orbital tether system deployment is studied. During the deployment of an orbital tether system the tether tension force control program is used that takes into account limitations on the deployment velocity. A parametric boundary problem is solved for the program of controlling the deployment of an orbital tether system. A kinematic scheme of the equipment, consisting of an engine that simulates the Earth’s gravitation and a tether deployment mechanism, is created. Based on the kinematic scheme, a dynamic scheme with control path feedback on tether deployment velocity and tether tension is created. The deviation control principle is implemented: control is realized on the deviation of the real value of the parameter under consideration from its program value. The magnification ratio of the controlled value deviation from the program values is used as the controlled value in transient optimization. The numerical simulation of the test bench operation performed in the MapleSim 7 environment shows acceptable quality of transient tether deployment velocity and tether tension.
