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:實際的復雜工業過程，往往具有大的時滯，例如：煉油廠催化裂化裝置的反應再生系統，其原料油預熱通過油漿換熱實現，因此時滯特別大.本文針對這一類大的時滯過程，設計了以動態矩陣控制為核心演算法的預測控制系統，運行實踐表明：這一控制方案比原pid控制在控制質量上有較大提高It is shown that the gam and alsphene in the seven catalytic stocks were not very high except in residual oil ; the saturate hydrocarbons in all seven were hig her ; aromatic contents were lower except in slurry oil and recycle oil, therefore, t he s even catalytic stocks except slurry oil and recycle oil are all good feedings of catalytic cracking unit
