Anti-disturbance Capacity Analysis and Verification for Biased Momentum Small Satellites

HJ-1A/1B and HY-1B satellites are biased momentum small satellites,whose control actuators use biased momentum wheels and magnetic bars.The control systems of these satellites are provided with some anti-disturbance capacity.In this paper,anti-disturbance capacity analysis and simulation for these biased momentum small satellites are presented.Furthermore,the accuracy and stability of the control systems are verified with on-orbit data.
