NCS中數(shù)據(jù)傳輸丟包與控制方法

解決數(shù)據(jù)包丟失是網(wǎng)絡(luò)傳輸?shù)囊粋€(gè)基本問題，NCS 中數(shù)據(jù)的丟失意味著會(huì)對(duì)控制系統(tǒng)
的穩(wěn)定性造成影響。本文研究了網(wǎng)絡(luò)控制系統(tǒng)中單包丟棄和多包丟棄的現(xiàn)象和描述方法，分析了一種實(shí)用的補(bǔ)償與控制方法。本研究可以看作是對(duì)NCS 延時(shí)研究的一個(gè)主要補(bǔ)充。在NCS 設(shè)計(jì)和實(shí)際使用過程中，正確對(duì)待丟包處理有時(shí)是提高系統(tǒng)穩(wěn)定性的一種有效措施。

Abstract：It’s a basic problem of network to solve data package dropout, data dropout may affect the system stability in NCS. The state and description method of single data package and multi data package dropout in NCS is put forward and a applied compensation and control method introduced in this paper. The results may be regarded as a main supplement of NCS delay. At the actual application, if data package dropout problem is treated rightly, it will be a effective means for increasing system stability sometimes.
