摘要
由于网络控制系统NCS引入网络后造成系统时延而造成系统的不稳定性。本文针对一类短时延NCS中,为保证系统的全局稳定问题,研究了该短时延系统的时延有界性。同时,证明了在输出反馈的条件下,分析了系统的闭环稳定性充分必要条件。最后,文章也通过Matlab对被控对象进行仿真实验,进而证明了文中的结论。
Since network was applied in NCS,it caused the un-stability of system because of the problem about system＇s delay. In this paper,it proved the boundness of system＇s delay to ensure system＇s global stability for a type of short time delay NCS. Meanwhile,it also analyzed necessary condition for system closed stability and simulated a controlled system to prove the result.
