研究了具有输入非线性的不确定时滞系统的无源滑模控制问题。采用滑模控制方法,一个控制器被设计可以保证系统的状态在有限时间达到切换面,同时使得滑动模态具有无源性和渐近稳定性的充分条件以线性矩阵不等式被获得,求解方便。最后,一个仿真例子说明了所提方法的有效性。
The problem of passive sliding mode control for uncertain time-delay systems subjected to input nonlinearity is investigated.Using the sliding mode control,a robust law is established such that the reachability of the sliding surface in the state space is guaranteed in a finite time,and the sufficient condition for the passivity and asymptotic stability of sliding mode dynamics is derived via linear matrix inequality(LMI).Finally,a simulation example is presented to verify the validity of the proposed method.
