Abstract

A sliding mode control-based robust control law is proposed to deal with the problem of spacecraft attitude tracking considering actuator misalignments and external disturbances. The control torque errors due to actuator misalignments are considered in the proposed control law, and its effects on attitude control performance are suppressed. Besides showing stability, explicit bound on the attitude tracking errors is given in terms of design parameters. Simulation results show the effectiveness of the proposed control scheme.
