    Multiple Spacecraft Formation Flying Control around Artificial Equilibrium Point Using Propellantless Approach by Lei Zhao, Changqing Yuan, Xiaoming Li, Jingjiu He

    Published 2022-01-01
    “…Thirdly, based on a new double power combination function reaching law, a fast integral terminal sliding mode control methodology (MFITSM) is ameliorated to achieve orbital tracking rapidly, which has better robustness against external disturbances and the buffeting effect during spacecraft propulsion simultaneously. To properly allocate control inputs, a novel optimal allocation scheme is designed to calculate the charge product of the spacecrafts and sail attitude angles, which can make the magnitude of the acceleration required from the Coulomb propulsion system minimum and avoid formation geometry instabilities by balancing electrostatic interaction between adjacent spacecraft. …”
