| 摘 要： | 基于模糊层次分析法,网络控制系统参照ISO/OSI模型,结合实际控制系统的需要进行了一定的简化,将数据传输的内部时延分为8种,外部延迟分为5种;通过求取某一层相对于总目标的相对重要度,得出了NCS时延的相对重要度,由此确定NCS的主要时延源和极小时延源.这种方法克服了对时延的盲目假设,以利于NCS的时延分析.

| Abstract: | Based on fuzzy analytic hierarchy process and the network control system model of ISO/OSI, the actual control system was simplified by dividing the data transmission internal latency into 8 kinds and 5 kinds of external delay. Through seeking some relative importance to the total goal, the NCS time - delay relative importance was obtained, from which the NCS＇ s main time - delay source and minimum time - delay source were determined. This method has overcome blind supposition of the latency, helping NCS＇ s latency analysis. |
