摘　　要：针对飞航平台稳定控制回路对象讨论Dahlin控制器设计问题,在复频域分析的基础上,探讨了二阶对象期望闭环传递函数的合理形式。通过对期望闭环传递函数和控制对象的分析,找到了导致二阶对象Dahlin控制器产生振铃的原因,给出了判定振铃产生的条件,并且提出了修正设计方法以及振铃现象中关键参数的选择方法。As viewed from the stable control loop of aerodynamic missile platform, this paper discusses the design of Daplin controller. Based on the complex frequency domain analysis, it studies the proper form of second-order objective expected closed-loop transfer function. By analyzing the expected closed-loop transfer function and controlled objective, the cause for resulting in ringing of Dahlin controller of second-order objective is found, the decision ringing condition is given, the design modification method is put forward and the selection problem of key parameters in the ringing phenomenon is solved.
