摘　　要：在保证闭环系统稳定的前提下,将被控对象看成控制器,控制器看成被控对象,从集合的角度研究了镇定区间对象族的控制器存在条件和设计方法,利用值集的概念和Youla参数化结果给出了镇定区间对象族控制器存在的充分条件.在强约束条件下,得到了控制器存在的充要条件.最后给出了鲁棒镇定控制器的设计方法.The existing condition of controller, which can stabilize plant family with parameter uncertainties, and its design approach are considered from the point of set. For designing controller stabilizing a given plant family, a reversing method is adopted by using the concept of value set and the result of Youla. The sufficient condition of existing controller stabilizing the given plant family is given. Under strongly constraint condition, the sufficient and necessary condition is obtained. At last, the design method of controller is provided.
