Robust Control of Networked System and Its Application

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.
