The invention provides a traffic flow stability control method and system considering feedback control of an electronic throttle valve. The method comprises the following steps: establishing a basic heterogeneous traffic flow car-following model; an electronic throttle valve feedback control item is constructed through the coupling relation of angles of throttle valves of two adjacent vehicles; a basic heterogeneous traffic flow car-following model is improved based on a control item, and a heterogeneous unbalanced traffic flow macroscopic model is established; introducing traffic flow density and speed disturbance into the macroscopic model, calculating a disturbance-containing function, and further calculating a traffic flow neutral stability condition; and the stability of the macroscopic model is judged by using a stability condition, and the stability of the macroscopic traffic flow system is improved by controlling parameter adjustment.
本发明提出了考虑电子节流阀反馈控制的交通流稳定性控制方法及系统,包括:建立基础的异质交通流跟驰模型;通过相邻两车节气门角度的耦合关系构建电子节气阀反馈控制项;基于控制项对基础的异质交通流跟驰模型进行改进,建立异质非均衡交通流宏观模型;将交通流密度及速度扰动引入宏观模型中,计算含有扰动的函数并进一步计算交通流中性稳定性条件;利用稳定性条件判断宏观模型的稳定性,并通过控制参数调节提高宏观交通流系统的稳定性。
