@@@@In order to overcome the problem of dead zone in automatic car steering control system, this study has developed a mixed logic dynamic vehicle model with dead zone characteristics using mixed logic. The model optimizes the steering control using the method of predictive control. The logic variables in mixed logic dynamic model take into account of each interval to determine the system dynamic equation. Model predictive control can forecast the output, optimize the rolling, and feedback the correction link. Therefore, the model can achieve an excellent control performance and robustness. The study results show that the mixed logic dynamic vehicle model with dead zone characteristics can achieve a better control effect and avoid steady-state error. The study provides a theoretical guidance for improving car driving safety and stability.
