我们提出了一种针对运输系统中扰动的局部化和衰减的控制策略。交通运输网络中突然的大扰动会导致冲击波的产生和传播，这些冲击波会在整个系统中传播，造成交通堵塞，降低系统吞吐量。通过考虑交通流的细胞传输模型，我们设计了一个最小能量控制器，利用车辆间通信将冲击波定位到高速公路的小路段，并在指定的时间内衰减它们。通过对加州I-210高速公路真实数据的仿真，说明了控制设计。
We present a control strategy for localization and attenuation of disturbances in transportation systems. Sudden and large disturbances in a transportation network can lead to the creation and propagation of shock waves which spread throughout the system causing jams and decreasing system throughput. By considering the Cell Transmission Model of traffic flow, we design a minimum-energy controller that exploits inter-vehicle communication to localize shock waves to small sections of the highway and attenuate them within a specified period of time. The control design is illustrated through simulations on realistic data from the I-210 highway in California.
