ABSTRACT

This paper presents a fuzzy model-based control algorithm for nonlinear interconnected cooperative adaptive cruise control system (CACCs). Firstly, a nonlinear model of the CACCs’ longitudinal movement is replaced by an equivalent Takagi-Sugeno type fuzzy model. Then, this paper designs a decentralized state feedback fuzzy controller to override the external disturbances such that the CACCs can achieve a good performance. Finally, the asymptotic stability and string stability of the nonlinear interconnected CACCs is guaranteed. The effectiveness of the proposed method is demonstrated by simulations.
