本文首先提出了一种避免城市路网交通拥堵的交通信号控制系统模型。该模型是可控的，可以考虑交通流的扰动和交通状况的变化。因此，所提出的模型被描述为具有多面体不确定性的线性系统。其次，将一种鲁棒控制方法应用于所提出的模型，以获得在不确定条件下的鲁棒稳定性和性能。提出的控制方法给出了实时全网交通信号系统的控制律。最后给出了一个算例，验证了该方法的有效性。
This paper first proposes a model of traffic signal control systems for avoiding traffic congestion in urban road networks. The model is constructed so that it is controllable, and disturbances of traffic flow and changes of traffic situations can be taken into account. As a result, the proposed model is described as a linear system with polytopic uncertainties. Next, a robust control method is applied to the proposed model so as to achieve robust stability and performance under the uncertainties. The proposed control method gives a control law for real-time and network-wide traffic signal systems. A numerical example is given to show the effectiveness of the proposed method.
