The control tactics of space voltage vector are investigated, and the simplified algorithm which judges the sector location of reference vector and calculates switch operation time is put forward. by analyzing the current hysteresis control, the relation between switch frequency, and hysteresis bandwidth and input inductance of pwm rectifier is deduced. by applying instantaneous power theory, the principle of pwm rectifier power control is analyzed, and the direct power control by matlab toolbox through estimating active power and reactive power with virtual flux is realized, and the simulation results prove that it is correct
對常用空間電壓矢量控制策略進行分析，提出了給定參考矢量所在區間判斷的簡化方法，以及電壓矢量作用時間的求取方法；分析了電流滯環控制策略，推導出開關頻率與滯環帶寬以及整流器輸入電感之間的關系；應用瞬時功率理論分析pwm整流器功率控制原理，通過虛擬磁鏈估計有功功率和無功功率，用matlab實現了直接功率控制，並驗證了該控制方法的正確性。 -
The result of the research of most switcl1 system including time divided switch systeln and space divided switch system, and its buffer strategy indicate that tilne divided switch system can not meet with the data transfer speed in fabric when design large scale high speed switch system because of the process of semiconductor
本論文定性分析了目前的分析交換系統，主要是時分交換系統和空分交換系統，以及空分交換結構對應緩存策略。由於目前光通訊技術的發展速度超過半導體工藝的進展速度，時分交換技術的分析結果表明它已經無法滿足高速大規模交換系統的要求。 -
Firstly, the task, structure, technology and function of the existing dispatch system were introduced, whose key technology is based on the tdm and time division switch like pstn. further, the developing direction of pstn is based on ip, the pocked switch system and network, and also the dispatch system of the manned space flight launch base will transmit multimedia information on ip
首先，介紹了現有調度系統的任務、結構、技術和功能，可以看出，其技術核心是時分多路復用和時分交換技術，現在公用交換電話網（ pstn ）正向基於ip的包交換系統和網路發展，載人航天發射場調度系統也將利用ip網路技術傳輸多媒體指揮信息。
