摘要

According to the power system of electric vehicle, this paper presents a method to reduce the vibration of the power system during the transmission with time delay filter. Firstly, we simplify the complex, motor control system and transmission system to low order system. Secondly, with experiment and estimation of system parameters, we use time delay filter theory to design several sorts of time delay filters. Finally, the experiment results of these filters determine the effect of vibration reduction and illustrate that time delay filter can reduce vibration of second order in high order time variable system as Electric Vehicle Power System.%针对电动汽车动力系统的简化模型,提出使用时滞滤波器减少动力系统中的传动振荡的方法.先将复杂的电机控制系统和变速传动系统简化成低阶(二阶)线性系统,通过实验估计系统参数,然后根据简化系统模型,依据时滞滤波器理论设计几种时滞滤波器.最后通过仿真和实验,验证时滞滤波器对传动振荡具有良好的抑制效果,间接说明时滞滤波器在汽车动力系统这类时变高阶系统中仍然能够滤除其中的二阶振荡环节.
