摘　　要：根据系统性能和鲁棒稳定性在复频域中研究控制器,并讨论将控制器扩展到不稳定系统,进而研究所引起的阻尼振荡,提出一种新的数字控制器的设计方法,可有效地减少阻尼振荡。The Dahlin controller is a distinctive algorithm for the control of single input/single output(SISO) plants with delay time.Dahlin controller was studied in the complexfrequency domain in terms of performance and robust stability.The possibility of extending the Dahlin controller to the control of unstable plants was discussed.The essential cause of ringing was investigated,and some ambiguous formulation is clarified.A new procedure is developed for digital controller designing.Compared with conventional methods,it provides a more effective method of eliminating ringing.Finally,an example is given to illustrate the new approach.

关 键 词：离散时间系统 DAHLIN控制器 阻尼振荡
