【摘要】 本文考虑了线性二次型高斯(LQG)分散控制系统求解中存在的维数扩展问题,提出了一种对标分离与结构分散相结合的算法。本算法把高阶系统问题化为低阶系统问题求解,能计算任意分散信息结构系统的准最优解。对电力系统的一个模型进行了计算,得到了分散结构的、线性的、有限维的状态估计和反馈律。更多还原

【Abstract】 In considering of the dimension enlarge problem which emerges in solving proc-ess of decentralized LQG control systems on algorithm combining time-scale seperationand decentralized structure is presented.This algorithm converts the high-order systemproblem into low-order system ones for obtaining solutions.It is possible to calculatethe guasi optimal solutions for arbitrary decentralized information structure systems.By calculating a power system model,the state estimation and feedback law with decentralized structure,linear and finite dimension are obtained.更多还原
