与传统点对点控制系统相比,由于网络的引入,使得控制系统中出现一些新问题,诸如网络时延、网络调度、包丢失及多包传输等。这些问题的存在使系统性能降低,甚至使控制系统不稳定。主要对以太网中存在的网络诱导时延进行分析和研究。 Compared with the traditional point-to-point control system, due to the introduction of the network, some new problems have emerged in the control system, such as network delay, network scheduling, packet loss and multi-packet transmission. The existence of these problems to reduce system performance, and even control system instability. Mainly on Ethernet network induced delay analysis and research.
