Abstract

This article investigates the problem of fixed/preassigned-time (FIT/PRT) containment consensus for multiagent systems (MASs) characterized by multidimensional nonlinear dynamics and unknown external disturbances, where the agents exhibit heterogeneous self-dynamics. A radial basis function neural network is initially constructed to approximate the uncharted nonlinear dynamics, thereby alleviating the heterogeneity among agents. Subsequently, several novel adaptive distributed strategies based on the saturation function are developed to suppress the chattering induced by the sign function. The FIT-based saturation controller is utilized to realize the containment consensus of heterogeneous MASs, and the corresponding consensus conditions are derived using the FIT stability theorem. Furthermore, an innovative PRT-based saturation controller is designed to achieve PRT containment consensus, enabling the settling time to be flexibly specified according to task requirements while maintaining finite control gains. This design fundamentally enhances the conventional time-varying infinite-gain control approach. Finally, the effectiveness of the proposed distributed control strategy and the derived criteria is verified through several simulation examples.

基于饱和函数的异构多智能体系统固定/预分配时间约束自适应控制

本文研究了具有多维非线性动力学和未知外部干扰特征的多智能体系统（MASs）的固定/预分配时间（FIT/PRT）包容共识问题，其中智能体表现出异质自动力学。初步构建了径向基函数神经网络来近似未知的非线性动力学，从而减轻了agent之间的异质性。随后，提出了几种基于饱和函数的自适应分布式策略来抑制符号函数引起的抖振。利用基于FIT的饱和控制器实现了非均质质量的包容一致性，并利用FIT稳定性定理推导了相应的一致性条件。此外，设计了一种创新的基于PRT的饱和控制器，以实现PRT遏制共识，使沉降时间能够根据任务要求灵活指定，同时保持有限的控制增益。该设计从根本上改进了传统的时变无限增益控制方法。最后，通过仿真算例验证了所提出的分布式控制策略和准则的有效性。

期刊介绍： This publication provides a systems-level, focused forum for application-oriented manuscripts that address complex systems and system-of-systems of national and global significance. It intends to encourage and facilitate cooperation and interaction among IEEE Societies with systems-level and systems engineering interest, and to attract non-IEEE contributors and readers from around the globe. Our IEEE Systems Council job is to address issues in new ways that are not solvable in the domains of the existing IEEE or other societies or global organizations. These problems do not fit within traditional hierarchical boundaries. For example, disaster response such as that triggered by Hurricane Katrina, tsunamis, or current volcanic eruptions is not solvable by pure engineering solutions. We need to think about changing and enlarging the paradigm to include systems issues.
