摘要:

城市交通拥堵是美国和世界各地许多城市面临的一个长期问题。它导致基础设施使用效率低下,以及车辆燃料消耗和排放水平增加。拥堵与延误交织在一起,因为道路使用者在路上浪费了宝贵的时间,这反过来又降低了生产力。研究人员已经开发并将继续开发工具和系统来缓解这一问题。网络边界控制就是这样一种工具,已经得到了广泛的研究。它试图控制进入保护区的车辆流量,以确保不会达到网络基本图(NFD)预定的拥堵状态。本文从滑模控制理论出发,提出了一种新的控制方法。它相对于比例积分控制器的主要优点包括:(1)最小的调节,(2)不需要对控制方程进行线性化,(3)不需要对NFD的形状进行假设,以及(4)能够处理各种需求曲线而无需重新调节控制器。滑模控制器的实现和拥挤的电网上进行了测试。结果表明,所提出的控制器产生全网络的延迟节省和分散拥塞有效。

英文摘要:

Urban traffic congestion is a chronic problem faced by many cities in the US and worldwide. It results in inefficient infrastructure use as well as increased vehicle fuel consumption and emission levels. Congestion is intertwined with delay, as road users waste precious hours on the road, which in turn reduces productivity. Researchers have developed, and continue to develop, tools and systems to alleviate this problem. Network perimeter control is one such tool that has been studied extensively. It attempts to control the flow of vehicles entering a protected area to ensure that the congested regime predetermined by the Network Fundamental Diagram (NFD) is not reached. In this paper, an approach derived from sliding mode control theory is presented. Its main advantages over proportional-integral controllers include (1) minimal tuning, (2) no linearization of the governing equations, (3) no assumptions with regard to the shape of the NFD, and (4) ability to handle various demand profiles without the need to retune the controller. A sliding mode controller was implemented and tested on a congested grid network. The results show that the proposed controller produces network-wide delay savings and disperses congestion effectively.
