摘要
In order to solve the coordinated cruise control of straddle rapid-transit vehicle formation, this paper proposes a distributed coordinated cruise control method of straddle rapid-transit vehicle formation based on the fixed-time theory. Firstly, the dynamic model of rapid transit vehicle formation is established to make clear the control aim of formation queue, the frame of distributed fixed-time coordinated cruise control is constructed, and the method in terms of the distributed and fixed-time coordinated cruise control of straddle rapid-transit vehicle formation is proposed. Secondly, the algebraic graph theory is presented to describe the communication topology of formation, and a distributed fixed-time terminal sliding estimator is applied to estimate the position and speed of the pilot formation. And also, based on the strength of Lyapunov stability theory, the author designed the distributed fixed-time sliding controller carefully, and then its stability has been successfully proved. At last, the acceleration and cruise simulation is carried out to verify the effectiveness of the proposed control method. © 2023 South China University of Technology. All rights reserved.
