城市交通信号灯的模糊控制器设计

The Design for the Fuzzy Control of Traffic Signal Light

模糊逻辑主要是通过模仿人的思维方式来精确表示和分析不确定、不精确的信息。它在解决一些实际问题中应用非常广泛。模糊控制能够摆脱精确数学模型的束缚,模仿人脑的逻辑推理过程来解决问题,适合使用在复杂性和随机性较大的控制系统。本文提出一种基于车辆等待时间的城市单路口交通模糊控制方法,只是提供了一种算法,一种设计思路。以通过岔口的平均车辆延误时间作为评价指标,衡量设计控制器的控制性能。

Fuzzy logic is to accurately show and analyse the inaccurate information mainly by copying man＇s way of thinking.So it is widely used to solve some practical problems.The fuzzy control can break away from the binding up of the exact mathematical model and solve problems by copying man＇s process of logical inference,and it is fit for utilizing the traffic control system for complexity and randomness.This article proposes a method of fuzzy control of traffic of simple rim communication based on the vehicle＇s waiting time. And a method of calculating and a train of thought for designing are provided in which the function of controlling design is measured by taking the average delay time of vehicle while passing the fork as the evaluating index.
