针对一类含有变时滞和非匹配不确定参数的随机广义Markovian跳系统,提出一种滑模控制的方案。首先构造不带跳变的切换函数,利用线性矩阵不等式给出该系统随机鲁棒渐近稳定的充分条件;然后,为使闭环系统的状态轨迹在有限时间内到达切换面,利用Lyapunov稳定性方法设计了滑模控制器及切换规则;最终使闭环系统产生稳定的滑动模态。数值算例验证了该方法的有效性和可行性。
針對一類含有變時滯和非匹配不確定參數的隨機廣義Markovian跳繫統,提齣一種滑模控製的方案。首先構造不帶跳變的切換函數,利用線性矩陣不等式給齣該繫統隨機魯棒漸近穩定的充分條件;然後,為使閉環繫統的狀態軌跡在有限時間內到達切換麵,利用Lyapunov穩定性方法設計瞭滑模控製器及切換規則;最終使閉環繫統產生穩定的滑動模態。數值算例驗證瞭該方法的有效性和可行性。

A sliding mode control scheme was proposed for a class of stochastic singular Markovian jump systems with time-varying delays and mismatched uncertain parameters.A switching function without Markovian jump were construc-ted at first, and a sufficient condition of the stochastically robust asymptotic stability was obtained for the system in terms of linear matrix inequalities( LMIs) .Secondly, sliding mode controllers and switching laws are designed by the Lyapunov stability method to make state trajectories of the closed-loop system reach switching surfaces in finite time. Finally, the stable sliding mode dynamics was resulted for the closed-loop system.The proposed scheme was testified to be effective and feasible by a numerical example.
