摘　　要：为了提高混动汽车(hybrid electric vehiclen,HEV)电动下工作效率,设计了一种混动汽车传动系统的扭振系统主动控制策略。完成状态空间拉普拉斯转换并设置前馈控制器,通过理想模型取代实际模型阻尼比。在Simulink软件中建立仿真模型,对比不同模型阻尼比引起的控制性能变化。干扰下仿真结果表明:系统中加入前馈控制器后能够有效减缓汽车加速阶段的速度波动程度,从而减小电机启动阶段的传动扭振,提升汽车行驶过程的稳定性并实现更快加速效果,有效提高了HEV传动系统抗干扰能力,具有良好的应用价值。To improve the working efficiency of the hybrid electric vehicle(HEV),an active control strategy of the torsional vibration system of the HEV transmission system is designed.After completing the state space Laplace transformation and setting the feedforward controller,the actual model damping ratio is replaced by the ideal model.A simulation model was established in Simulink software to compare the control performance changes caused by different model damping ratios.The interference simulation results show that the addition of a feedforward controller can effectively reduce the speed fluctuation in the acceleration stage of the vehicle,thus reducing the transmission torsional vibration in the motor start-up stage,improving the stability of the vehicle during driving and achieving a faster acceleration effect.This research can effectively enhance the anti-jamming capability of HEV transmission system and has good application value.
