Abstract :
To meet the requirement of the satellite attitude and orbit control system (AOCS) could recover control in abnormal conditions, A reconfigurable control system using variable-structure control and improved pseudo-inverse is developed based on the error quaternion non-linear model in this paper, which overcomes the no uniqueness of initial pseudo inverse matrix. Simulation shows that it could provide desirable control qualities in the event of one reaction wheel failure, and robust for disturbance.
