Abstract
This paper presents the design of a super-twisting sliding mode control system for the roll, pitch and yaw angle trajectory control of spacecraft, orbiting in elliptic orbits, using solar radiation pressure. The spacecraft is equipped with four solar plates for the purpose of control. First a robust control law for attitude trajectory tracking using feedback of the attitude angles and their first and second derivatives is derived. This finite-time stabilizing control law is formed by summing a nominal control signal involving tracking error and its derivatives with fractional exponents, and a signal generated by a super-twisting sliding mode disturbance observer (SMDO). The SMDO reconstructs the lumped uncertain vector function for synthesis. Then for the output feedback control, an observer is designed to obtain the first and second derivatives of the attitude angles. Simulation results show that the solar control system accomplishes precise trajectory control, despite uncertainties and the Earth's shadow, using only attitude angle measurement. © 2017, American Institute of Aeronautics and Astronautics Inc, AIAA.
