Abstract
Space Solar Power Station (SSPS) is a giant spacecraft to collect space solar energy and transmit electric energy to the ground by using the wireless transmission technology. As a concentrated space solar power station, SSPS via the Orb-shape Membrane Energy Gathering Array (OMEGA) system is comprised of the concentrator subsystem, the photovoltaic array subsystem and the transmitting antenna subsystem. In this manuscript, the comprehensive study on the coordinate kinematic among subsystems is carried out. Firstly, kinematic analysis and dynamic analysis are conducted. Secondly, under the condition of ideal attitude, the influence of the moving condition of the Photovoltaic (PV) array on the overall system is studied. Finally, the control ability for the deviation attitude caused by the acceleration process of the photovoltaic array is studied. The simulation results demonstrate the serious influence of the angular acceleration of the photovoltaic array on the system's attitude and the validity of the designed attitude control system.
