摘　　要：针对用SMITH预估器进行迟延补偿后的控制器设计问题,分析了迟延补偿误差的特性,讨论了迟延补偿后的控制器再设计的依据,提出了按照模型失配程度选择控制器设计的建议。通过仿真试验找出了最大迟延补偿误差产生的条件并证实了折中控制器设计方案的有效性。In accordance with the controller design lbr the control system with a SMITH p,＇edictor, the error dynamic characteristics for the dead-time compensation is analyzed, the controller design basis with a SMITH predictor is discussed, and the suggestion on the selection of design schemes according to the degree of model mismatch is put forward. The simulation tests show the occurrence condition of the maximum error for the dead-time compensation and the design of the compromise controller is effective.
