Abstract: In order to improve the reliability of attitude control with reaction wheel, a control law is put forward, which is based on one reaction wheel and three magnetorquers in different fixing mode. The simulation results show that the precision of attitude control is about 0.3°, when the reaction wheel is installed with a certain angle from X axis in XZ plane. The control method is applicable for micro-satellite. When the wheel is installed along the roll or yaw axis, the satellite attitude can still be controlled. The control method can be used to a sick satellite.

Key words: attitude control, non-biased momentum, wheel, magnetorquer
