Magnetorques and the biased momentum wheel are usual control actuators for microsatellite. The speed of the biased momentum wheel may incline to saturate under a disturbing torque or some demand. Aimed at reducing the probability of making the biased momentum wheel speed to saturate, a designed method of distributive control is proposed, which combines the speed control of the biased momentum wheel and the attitude control in the three-axis stabilization control stage. Through the design of the rational gains, the wheel speed control can be adjusted to be a low dynamic control, which lags far behind the attitude control. The method can optimize the biased momentum wheel speed and reduce the probability of the biased momentum wheel speed saturation. The simulation demonstrates the discussions and can keep the biased momentum wheel in a good state for control.
