Abstract:

Aiming at the problem that thruster fix error had strong interference on the satellite attitude, we designed a compact satellite propulsion system for attitude control algorithm. By modeling the control moment and disturbance moment, we analyzed the impact on the attitude control and got the thruster fix error angle combination in the worst case. We compared the control results of the three axis under different fix error angle through the computer simulation experiment. Experimental results show that attitude control algorithm has the capability of enveloping the worst case in orbit maneuver mode, and the control results are stable and meeting the accuracy demand.
