摘要:

本文针对具有耦合约束的分布式线性离散时间系统,提出一种新颖的无终端代价的分布式模型预测控制(MPC)公式以及相应的分布式综合方法。所提出的控制方案基于松弛动态规划,引入显式稳定性条件作为附加约束。因此,与其他相关方法不同,所开发控制器的系统稳定性不依赖于设计终端代价。然后引入一种分布式综合方法,在每个局部智能体内部局部处理稳定性约束。为了解决分布式MPC的底层优化问题,开发了一种无违例的分布式优化方法,通过约束收紧确保迭代过程中的可行性。数值示例表明,所提出的分布式MPC方法确保每个可行控制序列的闭环稳定性,每个智能体并行计算其控制输入。

英文摘要:

This paper presents a novel distributed model predictive control (MPC) formulation without terminal cost and a corresponding distributed synthesis approach for distributed linear discrete-time systems with coupled constraints. The proposed control scheme introduces an explicit stability condition as an additional constraint based on relaxed dynamic programming. As a result, contrary to other related approaches, system stability with the developed controller does not rely on designing a terminal cost. A distributed synthesis approach is then introduced to handle the stability constraint locally within each local agent. To solve the underlying optimization problem for distributed MPC, a violation-free distributed optimization approach is developed, using constraint tightening to ensure feasibility throughout iterations. A numerical example demonstrates that the proposed distributed MPC approach ensures closed-loop stability for each feasible control sequence, with each agent computing its control input in parallel.
