网络延时对网络控制系统的影响及其控制对策

The Effect of Network Delay on Network Control System and Control Strategy

随着网络控制系统理论及应用研究的不断进展,网络延时对网络控制系统的影响日益突出,它是恶化系统性能、导致信息不能准时到达、引起系统不稳定的重要因素.在对网络控制及其特点进行分析的基础上,研究了网络延时对网络控制系统的影响,并从减少网络延时的网络优化与调度策略、无模型智能控制策略、鲁棒控制策略等方面出发,对网络延时的控制对策进行了分析和探讨,为进一步有效地实施网络控制提供了可靠途径.

With development of network control system theory and applications, the influence of network delay to network control system should be considered. It is one of the most important factors of worsening system performance, delaying information not to arrive on time and arousing system unstable. For these problems, the effect of network delay on network control system is analyzed deeply on the base of analysis in network control and its characters. The control strategy of network delay is also analyzed and discussed from the aspects of network optimization, schedule strategy of decreasing network delay, model-free intelligent controller and robust control strategy etc. In conclusion, it offers a reliable approach to implement network control more effectively.
