摘要
现如今混合动力汽车是汽车领域的研发重点,建模与仿真技术是混合动力系统研发中的重要手段。发动机发电机组作为混合动力汽车电传动系统中的最重要组成部分,如何对发动机进行建模与仿真具有重要的意义。以串联混合动力汽车为例,分析了发动机在混合动力电传动系统中的作用,通过双PI控制建立了发动机动力学控制简化模型,基于MATLAB/Simulink进行了发动机系统可视化数字建模并进行了发动机功率跟随仿真,结果表明所建立的发动机控制模型具有良好的动态性能与稳态精度,适用于混合动力汽车控制策略的研究。
The engine is one of the most important parts of hybrid electric vehicle,so it is significant how modeling and simulation of engine system.Towards to the series hybrid electric vehicle the effect of engine is analyzed and dynamics simplified model is built based on double PI control.Visualization mathematics model by MATLAB/Simulink for engine system is built and system power following simulation is made.Simulation results show that the presented model of engine used in hybrid vehicle is suitable for hybrid vehicle control strategy research with dynamics property and steady precision.
