3 集散式控制系統(tǒng)dcs （distributed control system）

　　集散式控制系統(tǒng)亦稱為分布式控制系統(tǒng)。前已述及，計(jì)算機(jī)控制系統(tǒng)按結(jié)構(gòu)劃分，可以分為集中控制和分布式控制，集中控制指由單一的計(jì)算機(jī)完成控制系統(tǒng)的所有功能和對全部被控對象實(shí)施控制的一種系統(tǒng)結(jié)構(gòu)，其優(yōu)點(diǎn)是系統(tǒng)的整體性和協(xié)調(diào)性好，但對計(jì)算機(jī)的可靠性和性要求甚高;而分布式控制系統(tǒng)dcs則以多臺計(jì)算機(jī)分別承擔(dān)不同的控制功能和處理范圍，不僅其處理能力大大提高，而且將危及系統(tǒng)的因素降低。

　　傳統(tǒng)意義上的dcs系統(tǒng)的基本構(gòu)構(gòu)圖式如圖3所示。

　　圖中：c1，c2，……，cn為控制，f1，f2，……fn為反饋信息。對dcs系統(tǒng)而言，各控制單元之間沒有直接信息聯(lián)系，

　　各控制單元有自己的性能指標(biāo)，控制策略和算法，且其性能指標(biāo)和控制算法等由決策單元按優(yōu)化準(zhǔn)則調(diào)節(jié)給出。如果圖3中去掉決策單元，就成了分散控制系統(tǒng)（decentralized control system），它并不具備dcs的上述特性。

　　在工程中，dcs系統(tǒng)除完成控制功能，還要實(shí)現(xiàn)監(jiān)視、管理等其它功能，其系統(tǒng)組成框圖如圖4所示。

　　由圖4可見，dcs系統(tǒng)實(shí)際上是一種分級遞階結(jié)構(gòu)。各控制器完成過程現(xiàn)場的控制任務(wù)，根據(jù)控制對象特性，可以分別情況，采用順序控制，程序控制，模擬量控制等等，其控制策略與控制算法要隨被控對象與要求而定。數(shù)據(jù)采集器用于收集控制信息和被控過程的各種狀態(tài)信息，數(shù)據(jù)采集任務(wù)不但可由控制器完成，也可由一般儀表和邏輯箱完成。控制器和數(shù)據(jù)采集器在控制現(xiàn)場對信號進(jìn)行預(yù)處理后經(jīng)高速數(shù)據(jù)通道送到上級計(jì)算機(jī)和crt操作站，crt操作站是顯示操作裝置，監(jiān)控級（計(jì)算機(jī)）通過協(xié)調(diào)各控制器的工作，實(shí)現(xiàn)控制過程的動態(tài)優(yōu)化。管理級（計(jì)算機(jī)）具有管理功能，又兼具對監(jiān)控級實(shí)現(xiàn)監(jiān)控功能，它具有豐富的信息資源，能夠?qū)Ρ豢貙ο筮M(jìn)行監(jiān)控，制定計(jì)劃，進(jìn)行成本核算，對設(shè)備和人員進(jìn)行管理等，以實(shí)現(xiàn)被控過程的靜態(tài)優(yōu)化和綜合自動化。

　　分布式控制系統(tǒng)有以下主要特點(diǎn)：

　?。?） 采用分級遞階式控制

　　以微處理器為核心的基本控制器，不但能代替模擬儀表完成常規(guī)的模擬控制，并且能實(shí)現(xiàn)復(fù)雜算法控制和程序控制。在基本控制器內(nèi)可采用固化的應(yīng)用軟件，在控制現(xiàn)場對輸入輸出數(shù)據(jù)進(jìn)行數(shù)據(jù)處理，減少了信息的傳輸，大大減少了上級計(jì)算機(jī)的數(shù)據(jù)處理量，降低了對上級計(jì)算機(jī)的要求，使系統(tǒng)程序應(yīng)用較為簡單。

　?。?） 采用物理上的分散結(jié)構(gòu)，實(shí)現(xiàn)了分散控制

　　在現(xiàn)場就地安裝控制器，不僅節(jié)省了輸入輸出電纜的長度，同時(shí)減少了傳輸信號的干擾。在功能上各控制器各自為政，各自獨(dú)立完成各自的功能，使系統(tǒng)故障分散，從而使系統(tǒng)可靠性大為提高。

　　（3） 具有計(jì)算機(jī)的通訊系統(tǒng)，可實(shí)現(xiàn)綜合控制

　　高速數(shù)據(jù)通道的通信系統(tǒng)，實(shí)現(xiàn)了各控制器、監(jiān)控計(jì)算機(jī)和管理計(jì)算機(jī)的綜合控制，通過高速數(shù)據(jù)通道，能把各自為政的控制器與監(jiān)控計(jì)算機(jī)聯(lián)系起來，進(jìn)行協(xié)調(diào)控制。利用監(jiān)控計(jì)算機(jī)的運(yùn)算能力，能完成復(fù)雜的控制算法，以實(shí)現(xiàn)整體的優(yōu)化。利用管理計(jì)算機(jī)豐富的軟硬件資源和信息資源，實(shí)現(xiàn)計(jì)劃、管理、決策的優(yōu)化，從而實(shí)現(xiàn)整個(gè)系統(tǒng)控制的優(yōu)化。
