中文摘要：

针对一类具有网型拓扑结构的互联大系统,提出一种动态输出反馈多重叠鲁棒分散关联镇定方法.该方法将系统状态空间加以扩展,在扩展空间中将其分解为按循环逆序排列的一系列两两子系统对,并为每个子系统对分别设计使其关联稳定的鲁棒分散动态输出反馈控制器,将这些多重叠设计的控制器再收缩回原空间,实现控制律的协调.将该方法应用到一个四区域网型电力系统控制设计中,仿真结果验证了所提出方法的可行性和优越性.

英文摘要：

A multi-overlapping robust decentralized connective stabilization method based on dynamic output feedback is proposed for a class of large-scale interconnected systems with the netted topological structure. In this method, the state space of an interconnected system is firstly expanded. The system is divided into a series of pair-wise subsystems in cyclical inverse order in the expanded space. And the robust decentralized dynamic output feedback controllers of each pair-wise subsystem are respectively designed, so that the each pair-wise subsystem is connective stable. Then the designed repeatedly controllers of every subsystem are contracted to the original space. Coordination of the control laws can be achieved. Finally, the proposed method is applied to control design of a four-area interconnected power system with the netted structure. Simulation results show the feasibility and superiority of the proposed method.
