同时数据包丢失和时延的NCS分析与设计

Analysis and Design of NCS With Data Packet Dropout and Network-Induced Time Delay

针对同时存在网络诱导时延和数据包丢失的网络控制系统,提出了新的建模方法。在数据包丢失率一定时,根据更新控制器采用的信息不同,采用了两种不同的问题解决方案,分别建立了网络控制系统的动态系统模型,并分析了网络控制系统的指数稳定性,通过仿真实例验证了结论的正确性。

Aim at the NCS with data packet dropout and network--induced time delay, a new modeling method was proposed. With data--packet dropouts rate constant, according to information vary which controller update, two different schemes were adopted. Two models of asynchronours dynamical system of NCS were set up respectively, and sufficient conditions for the exponentially stability of the two different closed NCS models were derived. Simulation examples were given to illustrate the validity of the results.
