研究了一类具有时滞的不确定网络控制系统(NCS)的滑模控制.首先,用一种特殊的变换将不确定时滞系统化为非延迟不确定系统形式.然后基于Lyapunov稳定性理论及线性矩阵不等式(LMI)技术,以线性矩阵不等式的形式给出了该系统的一些新的稳定性判据.所提出的控制器能够使具有不确定性的时滞系统渐近稳定性,而且控制器结构简单,计算方便.最后通过数值模拟,验证了所设计方法的有效性.
A class of sliding mode control for uncertain networked control systems (NCS) with time-delay is studied. First, a special transformation is used to systematically transform the uncertain delay into a form of non-delay uncertain system. Then based on Lyapunov stability theory And linear matrix inequalities (LMI), some new stability criteria of the system are given in the form of linear matrix inequalities. The proposed controller can make the asymptotic stability of the system with time-delay uncertain, and The controller has the advantages of simple structure and convenient calculation.Finally, numerical simulation is carried out to verify the effectiveness of the proposed method.
