英文摘要
      The traffic signal control method based on iterative learning control can not effectively deal with the nonrepetitive real-time disturbance in the road network. Based on the iterative learning traffic signal control method, a mixed traffic signal control method based on iterative learning and model predictive control is proposed through combining the rolling optimization and real-time correction characteristics of model predictive control. The proposed method can effectively improve the traffic conditions of the road network by using the periodic characteristics of traffic flow and deal with the real-time disturbance through the advantages of model predictive control. Thus, the control efficiency of the traffic signals is further improved. The effectiveness of the proposed method is verified by simulation experiments. The experimental results show that the hybrid traffic signal control method based on iterative learning and model predictive control can more effectively balance the vehicle density in the road network, and further improve the traffic efficiency of the road network. Finally, the convergence of the proposed method is also analyzed.
