局部分布式H2状态反馈控制

Localized and Distributed H2 State Feedback Control

Jing Yu, Yuh-Shyang Wang, James Anderson

摘要:

分布式线性控制设计是大规模信息物理系统的关键。它通常是可取的,既施加信息交换(通信)的分布式控制器的约束,并限制传播的干扰到一个本地区域,而不级联到全球网络(本地化)。最近提出的系统级综合(SLS)理论提供了一个框架,这样的通信和本地化的要求,可以在控制器的设计和实现。在这项工作中,我们得到了本地化和分布式H2状态反馈控制问题的解决方案,而不诉诸有限脉冲响应(FIR)近似。我们提出的合成算法允许列明智的分解所产生的凸计划,因此可扩展到任意大规模的网络。通过数值模拟,我们证明了所提出的方法优于以前的方法的成本性能和计算时间。

英文摘要:

Distributed linear control design is crucial for large-scale cyber-physical systems. It is generally desirable to both impose information exchange (communication) constraints on the distributed controller, and to limit the propagation of disturbances to a local region without cascading to the global network (localization). Recently proposed System Level Synthesis (SLS) theory provides a framework where such communication and localization requirements can be tractably incorporated in controller design and implementation. In this work, we derive a solution to the localized and distributed H2 state feedback control problem without resorting to Finite Impulse Response (FIR) approximation. Our proposed synthesis algorithm allows a column-wise decomposition of the resulting convex program, and is therefore scalable to arbitrary large-scale networks. We demonstrate superior cost performance and computation time of the proposed procedure over previous methods via numerical simulation.
