摘　　要：建立电子节气门的分数阶动态模型,并对其有效性进行了数值仿真验证。通过基于dSPACE实时仿真系统的电子节气门试验平台采集节气门开度数据,并利用无向图分析采集数据的可靠性。借助MATLAB/Simulink软件搭建电子节气门的分数阶和整数阶动态模型,分析节气门开度数据与所采集试验数据在同工况下的相似度。分析结果表明,存在多个分数阶次使得分数阶动态模型的相似度高于同工况下的整数阶。In this paper,a fractional dynamic model of electronic throttle is established and its effectiveness is verified by numerical simulation.The throttle opening data is collected by the electronic throttle test platform based on dSPACE real-time simulation system,and the reliability of the collected data is analyzed by using undirected graph.The fractional order and integer order dynamic models of electronic throttle are built by MATLAB/Simulink software,and the similarity between the throttle opening data and the collected test data under the same working condition is analyzed.The results show that the similarity of fractional order dynamic model is higher than that of integer order under the same working condition due to the existence of multiple fractional order.
