MFAC based balance control for freeway and auxiliary road

摘要: 为了解决快速路主辅路交通密度不均衡造成的局部道路拥挤和资源浪费现象,本文提出了基于无模型自适应控制的快速路主辅路均衡控制方法,该方法中引入了均衡控制思想中的差值控制方法,该方法不受入口匝道和辅路交叉口的模型限制,利用入口匝道流率与交叉口离驶率输入数据和主辅路路段密度输出数据,即可实现强非线性快速路主辅路系统的无模型自适应控制,使主辅路达到系统级的密度均衡。Matlab平台上的仿真比较结果表明了这种控制方法的有效性。Abstract: In order to solve the question of traffic congestion and traffic resources wasting caused by the density difference between freeway and auxiliary road, the method of balance control for freeway and auxiliary road based on MFAC was proposed. This method introduced the difference balanced control theory and was not restricted by the entrance ramp and auxiliary road intersection model. Only depending on the ramp and intersection traffic flow rates as input data and the density of freeway and auxiliary road sections as output data, this method could achieve the model-free adaptive control on strong nonlinear freeway and auxiliary road system, reach to density equilibrium on freeway and auxiliary road system. The simulation results on the Matlab platform showed the effectiveness of the method.
