| 英文摘要 |
| This paper proposes a fast receding horizon estimation method for cooperative automated cruise control
(CACC) systems of connected vehicles monitored in cloud platform. The CACC system of connected vehicles is represented
by the longitudinal dynamic models of connected vehicle platoons, which reduces the requirements of state observability
of the CACC system of connected vehicles. Then the concept of “move blocking”is applied to design the noise block
structure of the receding horizon estimation algorithm, where the number of optimization variables of the optimization
problem is compressed to reduce the on-line computation. Furthermore, the Lyapunov stability theorem is used to prove
asymptotic stability of the estimation error system. Finally, the effectiveness of the proposed algorithm is verified by the
simulation of a five-connected vehicle fleet system. |
