摘    要：针对具有区域关联的电力系统负荷控制 问题，提出了一种基于H_∞设计分散状态反馈控制器的迭代算法．该算法主要是利用代数Riccati方程的重要性质，在保证闭环系统渐近稳定的前提下，对控 制器结构加以限制，从而使系统获得在某一性能指标下的次优状态反馈解．然后给出算例，说明该算法的应用

Abstract: A numerical procedure based on decentralized H_∞ state feedback controller is proposed to load control of a power system composed of several interconnected areas.The procedure mainly uses a new property of the algebraic Riccati equation.At the prerequisite of ensuring the stability of the overall controlled system,the system can obtain the suboptimal state feedback solution with structure constraint to the controller designed on the certain performance index.Then an example of two interconnected areas is solved and shows the application of the method.
