蒙特卡洛树搜索在网络控制系统周期调度设计中的应用

Application of Monte Carlo Tree Search in Periodic Schedule Design for Networked Control Systems

Burak Demirel, Arda Aytekin

摘要:

我们分析了由$N$独立的线性反馈控制回路组成的网络控制系统的闭环控制性能,共享一个与$M$通道($M<N$)的通信网络。采用产生周期性通信序列的调度协议的集中式调度器规定哪些反馈回路应该利用所有这些信道。在周期性调度协议下,我们推导出了一个二次函数形式的网络化控制系统的整体控制性能的量化解析表达式。我们还制定了一个给定的线性反馈控制子系统的集合的通信序列的离线组合优化。然后,我们应用蒙特卡罗树搜索,以确定这些通信序列,达到接近最佳的控制性能的周期。通过数值研究,我们证明了所提出的框架的有效性。

英文摘要:

We analyze the closed-loop control performance of a networked control system that consists of $N$ independent linear feedback control loops, sharing a communication network with $M$ channels ($M<N$). A centralized scheduler, employing a scheduling protocol that produces periodic communication sequences, dictates which feedback loops should utilize all these channels. Under the periodic scheduling protocol, we derive analytical expressions for quantifying the overall control performance of the networked control system in terms of a quadratic function. We also formulate the offline combinatorial optimization of communication sequences for a given collection of linear feedback control subsystems. Then, we apply Monte Carlo Tree Search to determine the period of these communication sequences that attain near-optimal control performance. Via numerical studies, we show the effectiveness of the proposed framework.
