摘　　要：网络诱导时延是影响网络控制系统稳定性和动态性能的主要因素.针对一类具有不确定性的网络控制系统,给出具有网络诱导时延及不确定性的被控对象模型,设计其滑模控制器,建立基于滑模反馈控制器的网络控制系统闭环模型.通过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.仿真例子验证了该方法的正确性和有效性.Network-induced delay is a main factor that influences the stability and the dynamical performance of networked control systems. For networked control systems with uncertainties, a controlled object model with network-induced delay and uncertainties is presented. A sliding mode controller is designed and the corresponding closed loop form of the networked control system is established. Applying Lyapunov method shows that the maximum allowable delay bound obtained can ensure the system＇s stability. Finally, a simulation example illustrates the feasibility and effectiveness of the proposed method.
