Samuel Mallick, Filippo Airaldi, Azita Dabiri, Bart De Schutter

AI总结:

本文首次将分布式MPC作为函数逼近器引入多智能体强化学习,通过重构集中式更新实现无偏的分布式Q-learning,并在数值算例中验证了有效性。

摘要:

本文针对具有凸多面体约束的线性系统,提出了一种新颖的多智能体强化学习(RL)方法。现有的强化学习工作已经证明了将模型预测控制(MPC)用作策略函数和值函数的函数逼近器的可行性。本文是首次将这一思想扩展到多智能体场景的工作。我们提出使用分布式MPC方案作为函数逼近器,其结构支持分布式学习和部署。随后我们证明,通过重构集中式学习更新,Q-learning更新可以在不引入非平稳性的情况下以分布式方式执行。该方法的有效性在两个数值算例上得到了验证。

英文摘要:

This paper presents a novel approach to multi-agent reinforcement learning (RL) for linear systems with convex polytopic constraints. Existing work on RL has demonstrated the use of model predictive control (MPC) as a function approximator for the policy and value functions. The current paper is the first work to extend this idea to the multi-agent setting. We propose the use of a distributed MPC scheme as a function approximator, with a structure allowing for distributed learning and deployment. We then show that Q-learning updates can be performed distributively without introducing nonstationarity, by reconstructing a centralized learning update. The effectiveness of the approach is demonstrated on two numerical examples.
