Event-Based Distributed Fixed-Time Resilient Control for Heterogeneous Vehicular Platoon Against Attack and Disturbances

Abstract

This article is concerned with the issue of distributed adaptive fixed-time fuzzy resilient control (DAFTFRC) for the heterogeneous connected vehicular platoon (HCVP) system subject to deception attacks and unknown external disturbances. Firstly, an effective fixed-time disturbance observer (FTDO) is introduced to quickly estimate the unknown external disturbance of the platoon. Then, the DAFTFRC framework is designed to satisfy the internal stability and the string stability under the deception attacks in a settling time by introducing the improved event-triggered mechanism (IETM). Correspondingly, by employing the IETM, the inter-event execution intervals are prolonged, and the execution rate of the actuator can also be significantly reduced. Ample and rigorous theoretical analysis proves the internal stability and string stability in sense of the practical fixed-time stability. Finally, the effectiveness of the developed scheme is substantiated by the comparison examples and the SUMO-MATLAB joint simulation platform.
