摘　　要：为了提高城市轨道交通信号控制的智能性和集成性,进行控制系统的优化设计,提出基于模糊控制算法的城市轨道交通信号控制系统设计方法.采用变结构PID模糊神经网络控制方法进行城市轨道交通信号控制规则的改进设计,根据交通信号的传输信道模型进行控制系统的信道均衡设计,采用自适应调度方法进行城市轨道交通信号的多线程调度,实现控制优化.在嵌入式环境下进行城市轨道交通信号控制系统的硬件设计,系统测试结果表明,采用该系统进行城市轨道交通信号控制的品质较好,控制收敛性较高,人机交互性较强.In order to improve the intelligence and integration of urban rail transit signal control,the optimal design of control system is carried out. This paper presents a design method of signal control system of urban rail transit based on fuzzy control algorithm and adopts variable structure PID fuzzy neural network control method to improve the design of signal control rules of urban rail transit. According to the traffic signal transmission channel model,the channel equalization design of the control system is carried out,and the multi-thread scheduling of the urban rail transit signal is carried out by adaptive scheduling method. The hardware design of the signal control system of urban rail transit is carried out in the embedded environment. The system test results show that the quality of the signal control system is good. The control convergence is high and the man-machine interaction is strong.
