Event-triggered quantized control of vehicle platooning system under disturbances and communication delay

To reduce communication load and save computational resources while ensuring the stability of a vehicle platoon system, an event-triggered quantized stability control method is proposed. Under the premise of significantly reducing communication frequency and computational demands, this method can achieve string stability under communication delays, data loss, and external disturbances. A model for the uncertainty of delays and disturbances in vehicle platoon systems is established, along with an event-triggered quantized collaborative control system. A global stability criterion for the vehicle platoon system is provided, and the proposed control method is validated through Matlab-Carsim joint simulations. Results show that, compared with the traditional platoon stability control, the proposed approach can maintain a spacing error of less than 0. 35 m and a speed tracking error of no more than 0. 28 m / s, even under maximum external wind speeds of 10 m / s, maximum communication delays of 0. 03 s, and up to 10 data losses, while achieving a reduction in control frequency of up to 66. 89% . © 2024 Southeast University.
