AI总结:

本文针对具有未知动态的高阶多智能体系统,提出了一种分布式优化方法,通过嵌入式控制设计将问题转化为输出稳定化问题,并设计了两种自适应控制器以在温和条件下驱动输出趋近于全局最优解,同时证明了参数估计向量在一定条件下收敛。

摘要:

在本文中,我们研究了一类具有未知动态的高阶多智能体系统的分布式优化问题。与现有针对积分器或线性智能体的结果相比,我们需要克服未知非线性和优化要求带来的困难。为此,我们采用嵌入式控制设计,首先将该问题转化为输出稳定化问题。然后,为这些智能体设计了两种自适应控制器,以在某些温和条件下驱动它们的输出趋近于全局最优解。最后,我们证明在某些已知的持续激励条件下,估计的参数向量收敛于真实参数向量。这些算法的有效性通过一个仿真示例得到了验证。

英文摘要:

In this paper, we study a distributed optimization problem for a class of high-order multi-agent systems with unknown dynamics. In comparison with existing results for integrators or linear agents, we need to overcome the difficulties brought by the unknown nonlinearities and also the optimization requirement. For this purpose, we employ an embedded control based design and first convert this problem into an output stabilization problem. Then, two kinds of adaptive controllers are given for these agents to drive their outputs to the global optimal solution under some mild conditions. Finally, we show that the estimated parameter vector converges to the true parameter vector under some well-known persistence of excitation condition. The efficacy of these algorithms was verified by a simulation example.
