Abstract : In this paper, the stability issue of networked system with dynamical topology in intelligent vehicle is studied. The systems are comprised by multi-vehicles coupled by vehicle network. The topological structure of vehicle network is subject to jump, and control signals are exchanged by the communication network with random network-induced delay. Firstly, the discrete-time state space equation for coupled intelligent vehicle with switching topology is modeled. Then, two output feedback controllers are designed by considering the coupling of controllers or not. In which, a new output feedback coupled-controller is designed in order to achieve decouple. Furthermore, the delay-dependent stability conditions on Lyapunov-functional method are given to guarantee the stochastic stability of the closed-loop networked system. Finally, a simulation experiment is executed to illustrate the designed method and verify the stability performance.

Keyword : Intelligent vehicle, jumping topology, network-induced delay, networked systems, output feedback control.
