摘要:

我们为具有状态反馈的偏序因果系统开发了H_2最优分散控制的完整状态空间解。我们的解基于对问题关键可分离性的利用,通过求解少量解耦的标准Riccati方程,实现了最优控制器的高效计算。我们的方法提供了对最优控制器结构的重要洞察,例如依赖于偏序集结构的控制器阶数界。在我们对控制器的状态空间刻画中,一个新颖的元素是一对显著的传递函数,它们属于偏序集的关联代数,互为逆,并且与沿偏序集不同路径的状态预测密切相关。通过数值例子说明了结果。

英文摘要:

We develop a complete state-space solution to H_2-optimal decentralized control of poset-causal systems with state-feedback. Our solution is based on the exploitation of a key separability property of the problem, that enables an efficient computation of the optimal controller by solving a small number of uncoupled standard Riccati equations. Our approach gives important insight into the structure of optimal controllers, such as controller degree bounds that depend on the structure of the poset. A novel element in our state-space characterization of the controller is a remarkable pair of transfer functions, that belong to the incidence algebra of the poset, are inverses of each other, and are intimately related to prediction of the state along the different paths on the poset. The results are illustrated by a numerical example.
