摘要: 基于快速路交通流分布参数系统模型,利用模糊逻辑整定PI控制器参数,提出了一种入口匝道模糊自整定PI边界控制方法。该方法可同时利用快速路交通流各个路段在时间和空间上的反馈信息,且其控制器参数可在线调整。仿真研究结果进一步说明了所提出方法的有效性和适用性。

Abstract: In this paper, based on a freeway traffic flow distributed parameter system model, a fuzzy selftuning PI boundary controller for ramp metering is designed. The proposed controller can fully use the current feedback information of time and space simultaneously, and the controller parameters can be tuned online. The simulation results further illustrate the effectiveness and appliciability of the proposed approach.
Key words: onramp metering; distributed parameter system; boundary control; PI controller; fuzzy selftuning
