Data-Based Output Synchronization of Discrete-Time Heterogeneous Multiagent Systems With Sensor Faults.

Abstract

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.
