Zusammenfassung:Vehicle safety issues and its systems dependence on electronics are rapidly increasing. In intelligent vehicles, rigid components are replaced with controlled x-by-wire systems including configurable electronic elements. In the paper, through complete modeling of Steer-by-wire (SBW) nonlinear dynamics, the chaotic motion of the system is elucidated by a new yaw stability control method. The designed chatter free Sliding mode controller (SMC) is used to synchronize chaotic motion of the SBW system. Following stability and robustness analysis, computer simulations show that the proposed control system is quite significant for nonlinear systems like the SBW system. Besides, the robustness of the SMC against exogenous disturbance protects vehicle from undesired slide and spin motions.
