例句與用法
- Fcc fluidized catalytic cracker
流體催化裂化裝置 - Abstract : large time delay exists in complicated practical processes . for example , in fccu ( fluidized catalytic cracker unit ) reactor - regenerator , the feed is preheated through heat exchanging from fractional column slurry , thus results in large time delay . a predictive control system is designed for such processes , where the kernal algorithm is dynamic matrix control . application results show that the control behavior is improved than original pid control
文摘:實(shí)際的復(fù)雜工業(yè)過(guò)程，往往具有大的時(shí)滯，例如：煉油廠催化裂化裝置的反應(yīng)再生系統(tǒng)，其原料油預(yù)熱通過(guò)油漿換熱實(shí)現(xiàn)，因此時(shí)滯特別大.本文針對(duì)這一類大的時(shí)滯過(guò)程，設(shè)計(jì)了以動(dòng)態(tài)矩陣控制為核心算法的預(yù)測(cè)控制系統(tǒng)，運(yùn)行實(shí)踐表明：這一控制方案比原pid控制在控制質(zhì)量上有較大提高
