Fuzzy Active Disturbance Rejection Attitude Control of Spacecraft with Unknown Disturbance and Parametric Uncertainty

Abstract

© 2015 SERSC. Based on active disturbance rejection control (ADRC) and fuzzy logic control, a control scheme for attitude maneuver control of spacecraft is proposed. In which a maneuver path is planned to reduce overshoot and improve rapidity, and an extended state observer is designed to cope with unknown disturbances and parameter uncertainties. Furthermore, in order to improve dynamic performance of the control system, the gains of the nonlinear feedback control law are adjusted by fuzzy control online. Simulation results have convincingly demonstrated the effectiveness and robustness of the proposed control scheme.
