Traffic Subarea Boundary Control Strategy Based on Nonlinear Traffic Flow Model
Urban traffic flow has complex nonlinear dynamic characteristics,which cannot be accurately described by a simplified linear traffic flow model.Therefore,in this paper,on the basis of considering the influence of perturbation on subarea boundary control,a nonlinear urban macroscopic traffic flow model considering perturbation is firstly established,so that the model can bet-ter describe the operation of actual traffic flow.Secondly,a subarea boundary control strategy based on iterative learning control is designed by combining the periodic characteristics of urban traffic flow operation,and the convergence of the iterative learning control law is analyzed by using the Lipschitz condition and partial derivatives.Finally,the effectiveness of the traffic subarea boundary control strategy based on the nonlinear traffic flow model is demonstrated by simulation cases.
