摘　　要：提出一种控制有界情况下状态单向收敛的滑模控制方法.对于二阶系统,单向收敛是指初始状态与状态到达滑动模态的位置位于相平面同一象限的过程.通过分析到达阶段的动态特性,揭示了状态非单向收敛的原因,并提出了一种单向收敛条件,给出了系统状态单向收敛的区域.将所提出的方法应用于具有单向收敛要求的交会对接控制系统,结果验证了所提出方法的有效性.A unidirectional convergence sliding mode control with bounded control is proposed. For second-order system, the unidirectional convergence means that the initial state and the reaching position on sliding mode are in the same quadrant of phase plane. The cause of non directional motion is revealed by analyzing the dynamic motion of the reaching phase. The unidirectional convergence condition is proposed, and the unidirectional convergence domain is obtained. The above control method is used in rendezvous and docking control system which needs unidirectional convergence, and the results show the effectiveness of the proposed control method.
