Abstract

This paper explores the consensus issue in second-order generalized nonlinear multiagent systems (MAS) that involve uncertain nonlinear dynamics and external disturbances from the system. Suppose that the uncertain nonlinear terms can be approximated by neural networks with nonlinear residues. Through the incorporation of localized adaptive observer and disturbance observer for each agent, we propose a distributed adaptive protocol to promote bounded consensus (BC) in the network. Due to the use of saturated functions and adaptive gains in the protocol, the chattering phenomenon is weakened. Finally, two simulation examples verify the results of the fully distributed adaptive bounded consensus protocol.
二阶不确定非线性多智能体系统的有界一致:一种分布式神经网络控制方法
研究了二阶广义非线性多智能体系统的一致性问题,该系统包含不确定非线性动力学和外部扰动。假设不确定的非线性项可以用具有非线性残数的神经网络来逼近。通过将每个智能体的局部自适应观测器和扰动观测器相结合,提出了一种分布式自适应协议,以促进网络中的有界共识。由于协议中使用了饱和函数和自适应增益,减弱了抖振现象。最后,通过两个仿真实例验证了全分布式自适应有界共识协议的结果。

期刊介绍: Applied Mathematics and Computation addresses work at the interface between applied mathematics, numerical computation, and applications of systems – oriented ideas to the physical, biological, social, and behavioral sciences, and emphasizes papers of a computational nature focusing on new algorithms, their analysis and numerical results. In addition to presenting research papers, Applied Mathematics and Computation publishes review articles and single–topics issues.
