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
