In this article, the output synchronization of heterogeneous multiagent systems with sensor faults is considered. To detect and tolerate the faults, a number of detection mechanisms and fault-tolerant controllers (FTCs) have been proposed. Whereas, the existing methods require the precise model and they cannot be used when model information is unknown. Moreover, some designed parameters are required for the fault information in existing FTCs. To solve the above problems, the data-based detection mechanism and data-based FTC are proposed in this article. The disadvantage of inapplicability to unknown system model is overcome by the proposed methods. Furthermore, the fault information in the proposed controller is directly acquired from system data, where the additional parameters to be designed are avoided. Finally, the validity of the presented methods is shown via simulation example.

具有传感器故障的离散时间异构多智能体系统的基于数据的输出同步


在本文中，考虑了具有传感器故障的异构多智能体系统的输出同步。为了检测和容忍故障，人们提出了多种检测机制和容错控制器（FTC）。而现有的方法需要精确的模型，并且在模型信息未知的情况下无法使用。此外，现有FTC中的故障信息需要一些设计参数。针对上述问题，本文提出了基于数据的检测机制和基于数据的FTC。所提出的方法克服了不适用于未知系统模型的缺点。此外，所提出的控制器中的故障信息直接从系统数据获取，避免了需要设计的附加参数。最后通过仿真算例证明了所提方法的有效性。
