摘要
利用模糊逻辑控制器实时地调节高速公路入口匝道, 该控制器由模糊规则库、模糊生成器、模糊消除器等组成, 控制器的输入量来自入口匝道以及上下游的检测器, 输出是入口匝道的调节率. 这种模糊逻辑控制器的参数( 如规则库中规则的权值) 可以调整, 使之与不同的入口匝道相适应. 最后给出了仿真结果.
A real_time on_ramp control strategy is presented for freeway traffic by using a fuzzy logic controller, which consists of the fuzzy rule base, the fuzzifier, and the defuzzifier. This controller uses 6 inputs measured by several sensors built in the upstream , downstream and on_ramp in the freeway. The output is the metering rate of the on_ramp control. The parameters of such a controller can be adapted to an on_ramp. Some computer simulation results are also given in the paper.
