Future generation mission of satellites is to understanding global environment extensively and disaster monitoring in an acute situation and so on. Therefore, satellites need to observe given observation points in given times. Requirements of satellites attitude control are high speed attitude changes and high stability, and requirements of attitude control actuator are high torque and high resolution torque. Currently, Attitude control actuator which is able to generate high torque is only Control Moment Gyro. However, CMG generates disturbance torque because of complicated structure and dynamics interference. In this study, modeling disturbance torque in gimbal axis and analyzing control torque error make understanding effect of control torque error against satellites attitude control. In addition, Use of disturbance estimation observer and disturbance elimination filter has control over control torque error.
