摘　　要：研究基于包含原理的大系统重叠结构分解方法对系统控制性能的影响。以两区域互联电力系统为例,在不同的重叠分解方法下,利用鲁棒镇定的LMI算法,对系统进行了控制仿真。研究表明,不同的重叠结构分解方法,使系统具有不同的动态性能和鲁棒性能,并且动态性能的鲁棒性能不可兼得,因此,在进行系统设计时应该折衷考虑。The influence of overlapping structure decomposition method based on inclusion principle on control properties of interconnected large-scale systems was studied. In order to analyze expediently, a two-area overlapping interconnected power system was taken for example, the control simulation of the system was done according to robust LMI algorithm under different overlapping structure deconmposition methods. The research shows that there are different dynamic properties and robust properties for different decomposition methods, and the perfect dynamic properties and robust properties cannot be obtained simultaneously. Therefore, the compromise strategy should be considered when the control system is designed.
