This article considers the consensus problem of uncertain multiagent systems, which is addressed by neuroadaptive impulsive control schemes. The proposed control schemes indicate that the communication among agents only occurs impulsively, while the dynamics uncertainty is addressed by adaptive schemes using neural networks. Based on such approaches, two specific control schemes are designed. One is that with impulsive feedback, the control scheme uses continuous-time information, which implies that the adaptive process is continuous over time. Another is that by adopting sampled information, the update of all systems, including the feedbacks on agents, the update of neural networks, and the estimation for uncertainty, can be executed only at impulsive instants. The latter case can reduce the energy cost for communication and control, but extra assistant systems are required. The estimation and consensus prove to be achieved with errors if some conditions are fulfilled. Numerical simulations, including a practical system example, are presented.
本文考虑了不确定多智能体系统的一致性问题,该问题通过神经自适应脉冲控制方案来解决。所提出的控制方案表明,智能体之间的通信仅在脉冲时刻发生,而动力学不确定性则通过使用神经网络的自适应方案来解决。基于这些方法,设计了两种具体的控制方案。一种是具有脉冲反馈的方案,该控制方案使用连续时间信息,这意味着自适应过程随时间是连续的。另一种是通过采用采样信息,所有系统的更新,包括智能体上的反馈、神经网络的更新以及不确定性的估计,都只能在脉冲时刻执行。后一种情况可以降低通信和控制的能量成本,但需要额外的辅助系统。如果满足一些条件,估计和一致性被证明可以在有误差的情况下实现。给出了数值模拟,包括一个实际系统示例。
