摘　　要：研究对象族的同时镇定问题 ,设计出同时镇定两个选定对象的含参数控制器 .其基本思想是找到两个特殊对象 :对象族的标称对象和“最坏点”对象 ,据此设计鲁棒镇定对象族的含参数控制器 .由于引入了参数 ,使得通过已有的方法设计鲁棒控制器成为可能 .根据对象族系统的稳定性理论确定控制器中的参数 ,把设计控制器的问题转化成稳定性检验问题 。Problem of simultaneous stabilization of a plant family is studied. A controller including a parameter is designed to stabilize simultaneously two specified plants of which one is a nominal plant while the other a 'worst point' plant. The basic idea is to find the two specified plants and use them to design a robust controller including the parameter. Since the parameter is introduced, the robust controller can be designed using existence methods. The parameter in the controller can be obtained using the theory of stability of plant family system. Hence, the problem of designing a controller is converted into the problem of checking the stability. The controller can be designed by simultaneously stabilizing the plant family and determining the parameter in the 'worst point' plant.
