摘要:

在随机系统中,针对定量时间逻辑约束的最优控制合成可以表述为线性规划问题。然而,集中式合成算法无法扩展到许多实际系统。为解决这一问题,我们提出了一种基于分解的分布式合成算法。通过将大规模随机系统建模为马尔可夫决策过程分解为一组相互作用的子系统,将原始控制问题表述为具有稀疏约束矩阵的线性规划问题,通过分布式优化方法进行求解。此外,我们提出了一种分解算法,能够自动利用给定大规模系统中可能存在的模块化结构。我们通过机器人运动规划示例展示了所提出的方法。

英文摘要:

Optimal control synthesis in stochastic systems with respect to quantitative temporal logic constraints can be formulated as linear programming problems. However, centralized synthesis algorithms do not scale to many practical systems. To tackle this issue, we propose a decomposition-based distributed synthesis algorithm. By decomposing a large-scale stochastic system modeled as a Markov decision process into a collection of interacting sub-systems, the original control problem is formulated as a linear programming problem with a sparse constraint matrix, which can be solved through distributed optimization methods. Additionally, we propose a decomposition algorithm which automatically exploits, if exists, the modular structure in a given large-scale system. We illustrate the proposed methods through robotic motion planning examples.
