摘要：
The paper investigates a vehicular platoon control problem with uncertain parameters and unknown disturbances, this method is able to achieve stability of the platoon control system in a finite time. For the predecessor-following and bidirectional information flow topologies, a new quadratic spacing strategy is introduced to achieve traffic flow stability. And then based on the nonlinear terminal sliding mode control and finite time stability theory, two distributed adaptive terminal sliding mode control schemes are presented to ensure the string stability and strong string stability, and the adaptive control law is designed to deal with the influence of uncertain parameters and exogenous disturbances. Finite time stability and string stability of the system are analyzed by constructing the Lyapunov function. Finally, the effectiveness of the proposed control scheme is demonstrated by numerical simulations. The results show that the proposed method can guarantee the string stability, traffic flow stability, and ensure all the states stabilized in a finite time. © 2023 South China University of Technology.
