文档介绍：基于元胞传输模型的模糊控制器设计与仿真
摘要
20世纪80年代以来,我国的经济快速发展,高速公路发挥了重要的作用。但随着机动车辆以几何级的数量增长,交通拥挤成为了社会上的热点问题。交通拥挤不仅会引起车辆延误,扰乱交通秩序,而且还会破坏人们的生活质量。针对这个问题,本文设计了基于元胞传输模型的模糊控制器,并把它运用在高速公路匝道控制上,进而控制进入高速公路主干道的车流量。本论文首先介绍了有关模糊控制的理念,接着重点介绍了元胞传输模型的原理,该原理能很好反映交通流的动态,并根据元胞传输模型设计了一种用于高速公路匝道控制的模糊控制器。最后应用MATLAB软件进行仿真,仿真的结果表明,该控制器具有较好的动态和稳态性能,能有效提高线路的通行能力,实现车辆快速,安全地运行。

Abstract
Since the 1980s, the freeway has played an important role in China's rapid economic development. But the number of motor vehicles with geometrical level growth, traffic congestion has e a social heat issues. Traffic congestion not only causes vehicle delays, and but also destroys the rule of traffic, destroys people's quality of life. Face to this question, this paper designs a fuzzy controller based on cell transmission model, and applys it on the freeway on-ramp control in order to control entering freeway traffic. The paper first starts to introduce the concept of fuzzy control, and then focuses on the principle of cell transmission model, which can well reflect the dynamic of traffic flow, and based on this a kind of fuzzy controller has been designed for freeway ramp control. Finally MATLAB software is used for simulation. Simulation results show that the controller has good dynamic and steady state can effectively improve the road capacity and make vehicles travel quickly and safely.
