入口匝道调节是快速路交通控制中较有效的一种方式,现基于快速路交通系统的常微分模型,设计了一种新的入口匝道的模糊自整定PI控制方法,充分利用了上游路段流入的交通流量和向下游路段流出的交通流量信息进行控制律更新,有效抑制了系统扰动等不确定性因素的影响。设计了相应的模糊控制逻辑,实现了复杂交通系统实际控制过程中的PI控制器参数的模糊自整定。仿真研究中,与传统PID和ALINEA方法进行了充分比较,说明了所提出方法的有效性。
On-ramp regulation is a more effective way to control traffic on expressways. Based on the ordinary differential model of expressway traffic system, a new fuzzy self-tuning PI control method for on-ramp is designed, which makes full use of the inflow Traffic flow and the flow of traffic to downstream sections of the control law update, effectively suppressing the system disturbance and other uncertainties. The corresponding fuzzy control logic is designed to realize the fuzzy self-tuning of PI controller parameters in the actual control of complex traffic system. In the simulation, a sufficient comparison with the traditional PID and ALINEA methods shows the effectiveness of the proposed method.
