摘要: 为消除常值干扰的影响,提出了一种具有饱和积分项的类PID姿态控制律.所提出的控制律不仅可以消除常值干扰带来的影响,并且由于积分项具有饱和约束,该控制律可以防止控制量由于积分项的持续积分而变得过大.利用前向系统的相关理论,严格证明了闭环系统的全局渐近稳定性质,并给出了相应的充分条件.仿真验证了该方法的有效性.

Abstract: A new PIDlike attitude control law with saturated integrals is proposed for the control of spacecraft. The control law can not only eliminate the influence of constant disturbances, but prevent the control torque from getting too large by means of saturation constraint on the integrals. With the associated theory of forwarding system, it is rigorously proven that the closed loop is globally asymptotically stable, and the corresponding sufficient conditions of the relevant parameters are also derived. Numerical simulations demonstrate the effectiveness of the proposed approach.

Key words: attitude control, PIDlike control, saturation control
