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. Aiming at a kind of interconnected large-scale system with mesh topology, this paper proposes a dynamic output feedback multi-overlap robust decentralized association stabilization method which expands the system state space and decomposes it in the extended space into cyclic order A series of two-to-two subsystem pairs are designed for each subsystem. Robust decentralized dynamic output feedback controllers are designed for each subsystem to stabilize them. The controllers of these multiple stacks are contracted back to the original space to achieve the coordination of the control law. The method is applied to the design of a four-zone grid-based power system. The simulation results verify the feasibility and superiority of the proposed method.
