| 摘 要： | 研究了一类非匹配不确定离散广义系统的准滑模控制问题。给出了带有扰动补偿的离散广义趋近律,消除了常规滑模控制中不确定项必须有界的限制,且不必满足匹配条件。所设计的滑模控制在有限时间内可达切换面,减小了准滑动模态带宽,有效地削弱了系统抖振,改善了系统动态品质。数值算例验证了该方法的可行性与有效性。

| Abstract: | The problem of quasi-sliding mode control for mismatched discrete singular systems with internal parameter perturbation and external disturbance is considered.A discrete singular reaching law with disturbance compensation is designed to eliminate the restriction of the system uncertainties is bounded and the satisfaction of matching conditions compared with conventional sliding mode control.A discrete singular sliding mode controller is designed by applying the reaching law,which can guarantee the system to... |
