针对挠性卫星控制受限问题，提出一种新的姿态控制方法．根据控制受限情况，确定逐步递阶变结构控制，每一步控制目标的设定都使得控制输入在限定的条件下，从而构成一个等价的控制不受限的变结构控制系统，满足滑动平面的到达条件．
Aiming at the limitation of flexible satellite control, a new attitude control method is proposed. According to the limited control situation, the step-by-step variable structure control is determined. The control targets are set under a limited condition in each step, so as to form an equivalent variable structure control system with unlimited control, which satisfies the sliding plane Arrival conditions.
