连续线性时不变系统的网络滑模控制

Sliding-Mode Control Based on Network for Continuous Linear Time-invariant System

研究具有网络诱导时延的网络控制系统滑模控制器设计及稳定性分析问题。针对一类具有网络诱导时延的连续线性时不变被控对象模型,设计其网络滑模控制器,建立基于网络滑模控制器的闭环控制系统模型。Lyapunov方法证明,所得最大允许时延能够保证闭环网络控制系统稳定。仿真结果表明控制器设计的合理性,所得最大允许时延上界保守性更弱。

This paper researches the design of sliding-mode controller and stability problem for networked control systems with network-induced delay is studied.Aiming at continuous linear time-invariant system with network-induced delay,its network-based sliding-mode controller is designed and the corresponding closed loop form of the networked control system is established.By Lyapunov method,it is proved that the maximum allowable delay bound obtained in this paper can ensure the system's stability.Simulation results indicate that the controller proposed is reasonable and the maximum allowable delay bound given in this paper is less conservative.
