交通控制不仅是一个实时的控制系统而且是一个具有随机性、非线性、不确定性的复杂系统,该篇讨论了运用PLC(可编程逻辑控制器)控制技术和模糊控制方法的交通信号控制系统并讨论了如何采用与计算机之间的通讯链接技术完成交通对象的复杂控制和运用模糊控制原理,将人的控制经验及推理过程纳入系统自动控制当中,使车辆行驶和道路导航实现智能化。
Traffic control is not only a real-time control system but also a complex system with randomness, nonlinearity and uncertainty. This article discusses the traffic signal control system using PLC (controllable logic controller) control technology and fuzzy control method And discussed how to use the communication link technology with computers to complete the complex control of traffic objects and the application of fuzzy control theory to integrate people’s control experience and reasoning into the system automatic control so as to make the vehicle travel and road navigation intelligent.
