研究和分析了网络控制系统（NCS）中同步误差理论，在局域网（LAN）中，网络控制系统的稳定性主要受通信延迟、带宽限制、包丢失和同步误差这四个方面影响，而同步误差延迟的时间长短对网络控制系统稳定性的影响尤为严重。本文主要通过数学模型检测和识别同步误差，并对有无同步误差情况下所得到的脉冲响应进行研究与分析，来观测网络控制系统稳定性的高低，从而对有无同步误差的网络控制系统的稳定性做出评估。

In this paper, the theory of synchronization errors in network contrcol system is studied and analyzed. In LAN,the main impacts of network control system performance are communication latency,bandwidth limitations,pack-et loss and synchronization error, but synchronization error in the NCS is more important. The synchronization error is detected and identified by using some mathematical models. Also analyzing the impulse response of the system can be changed when having synchronization errors. Thus the system performance is affected and an accurate assessment for the stability of the system can be made.
