Abstract

Abstract: 　A variable structure output feedback control method with disturbance compensation is presented under control torque saturation for the flexible spacecraft.In this method,the variable structure output feedback control suppresses the vibration of flexible appendages,the unknown dynamics and disturbing torques are estimated by an extended state observer and are compensated on line.The simulation results show the method is effective.

Key words: flexible spacecraft, variable structure control, output feedback, extended state observer
