时滞系统用于现场监控中的稳定性研究

Stability research of neutral time-delay system used on scene control

为了解决工业现场监控系统中网络通讯的不确定时滞问题,构造一个结构不确定的中立型变时滞系统的李雅普诺夫泛函,根据李雅普诺夫第二方法判定其渐近稳定的条件,通过MATLAB仿真计算出时滞可允许的最大上界,基于此时滞标准修改通讯协议保证其稳定运行。

In order to resolve uncertain time-delay problem of network communication in industrial scene control system, this paper created a new uncertain structure neutral variable time-delay system Lyapunov function, according to Lyapunov Second Method judged its asymptotic stability condition, then demonstrated that the math model can reduce the conservatism of allowable maximum upper bound by using MATLAB, referred a theory for the software stable running.
