单交叉口四相位模糊控制器的设计

在城市交通中,交叉口控制由于交通流的时变性、随机性和不确定性等,使得系统的基于模型的控制理论与方法难于取得良好的控制效果,因此,智能控制理论成为交叉口控制研究的热点。文中设计了一个考虑右转车对非机动车影响的四相位的交叉口两级模糊控制器,有效的克服了常规控制方式的缺点。通过仿真证明了其控制效果要优于常规控制方式和单一优化相序或相位的普通模糊控制器。

The Design of Four-phase Fuzzy Controller for Isolated Intersection

In urban traffic, the time-varying, random and uncertainty of intersection control traffic flow, makes the system control theory and control method based on the model difficult to obtain good results. Therefore, intelligent control theory becomes the central issue of intersection control research. An intersection two-stage fuzzy controller of four-phase is designed, which can overcome the shortcoming of conventional control effectively. The simulation shows that its control effect is superior to conventional control methods and the ordinary fuzzy controllers which only optimize the single-phase sequence or phase.
