摘要
通过引入动态控制系统,根据城市交叉路口交通状况复杂、多变、随机性强的特点,应用模糊控制的方法,对交通信号灯的线控和面控系统中周期长度、相位差、绿信比的控制进行了分析研究。提出了一种双向行车道路上相位差的确定方法,并用模糊控制和模糊神经网络控制技术对其实施控制。通过磁感线圈数据采集、模糊化、模糊规则进行模糊推理、解模糊、控制输出,实现智能化控制。
The dynamic control system is introduced. On the basis of the urban intersection＇s characteristics of complexity, flexibility and strong randomness and through the application of fuzzy control methods, the control of the cycle length, phase difference and split of the traffic lights and side-by-wire control system is an- alyzed. A method for the determination of phase difference in the two-lane road is proposed and fuzzy control and fuzzy neural network technology and control technology are used to control their implementation. Data acquisition of the magnetic sensing coil, fuzzilization and fuzzy rules are applied for fuzzy reasoning, fuzzy solution, and control output, and for the realization of intelligent control.
