交通信号控制机是用于城市交叉路口控制红、绿、黄灯色信号来指挥交通的装置,被控制对象是交叉路口的交通流过程。由于被控对象的不确定性和时变性,难于用数学模型描述,很难找到最优控制律。目前,多采用定时控制,控制效果不佳。我们采用智能控制原理于1989年10月研制成功自学习智能式交通信号控制机。该机在现场连续可靠运行已三年。运行结果表明其性能优良、控制效果好。本文介绍该机的原理、结构及应用情况。
Traffic signal control machine is used in urban intersection control red, green and yellow light color signal to direct traffic devices, the object of control is the traffic flow at the intersection. Due to the uncertainty and time-varying of controlled objects, it is difficult to describe with mathematical models and it is difficult to find the optimal control law. At present, the use of timing control, poor control. We adopted the principle of intelligent control in 1989 October successfully developed self-learning intelligent traffic signal control machine. The aircraft in the field continuous and reliable operation has been three years. Operation results show that its excellent performance, good control effect. This article describes the principle of the aircraft, structure and application.
