在这份报纸，为不明确的交换时间延期系统的一个类与被动滑动模式控制(SMC ) 的问题被学习。借助于多重 Lyapunov 功能技术，一个延期依赖者为分系统的线性滑动表面的存在的足够的状况要用体力地在交换滑动模式动力学的答案在哪个是被推出在一条基于状态的切换法律下面指数地稳定、被动。而且，滑动模式控制器被设计在有限时间驾驶系统轨道到分系统的预定义的滑动表面上。最后，一个数字例子被提供说明建议方法的有效性。

英文摘要：

In this paper, the problem of sliding mode control （SMC） with passivity for a class of uncertain switched time-delay systems is studied. By means of the multiple Lyapunov functions techniques, a delay-dependent sufficient condition for the existence of linear sliding surface of subsystem is deduced in which the solution to the switched sliding mode dynamics is robustly exponentially stable and passive under a state-based switching law. Moreover, the sliding mode controller is designed to drive the system trajectories onto the predefined sliding surface of subsystem in finite time. Finally, a numerical example is provided to illustrate the effectiveness of the proposed method.
