滞后中立型关联控制系统的滑动模变结构控制

The Sliding Mode Variable Structure Control of Neutral Interconnected Control Systems with Delay

本文设计了滞后中立型非线性关联控制系统的滑动曲面和分散滑动模控制器，每个子系统的控制器仅用到其局部状态信息．在滑动曲面和分散滑动模控制器可实现的条件下，在子系统中由Riccati方程的描述得到了可实现滑动模控制器的一个充分条件．该条件等价于由分散状态反馈镇定的条件．从而，本文的结果比以前的工作更合适，且可实现减少设计的保守性．

A sliding surface and a decentralized sliding mode controller are designed for a class of neutral nonlinear interconnected control system with delay,where the controller of each subsystem needs only local state information to work. A sufficient condition under which the sliding surface and a sliding mode controller can be achieved is obtained in terms of the Riccati equation on the subsystem level. The condition is equivalent to the stabilizability condition by decentralized state feedbacks. Thus,the results in this paper are more reasonable and less conservative than those reported in previous works.
