摘要: 串联式混合动力履带车辆前后功率链功率是否平衡,对车辆的动力性影响很大。针对实车急加速工况直流母线电压被拉低影响车辆动力性问题,开展串联式混合动力履带车辆急加速工况功率平衡控制策略研究。基于不同驱动电机外特性下系统波动情况,以及车辆行驶功率需求和发动机-发电机组响应特性,提出一种发动机-发电机组稳压和DC/DC-蓄电池组补偿的功率平衡控制策略,并通过实时仿真验证。实验结果表明,该策略可以平衡急加速工况前后功率链功率,直流母线电压波动范围-4.6%~2.36%,能够很好地保持系统稳定性。

Abstract: The power balance of front and rear power chains of series hybrid tracked vehicle has a great influence on the dynamic performance of the vehicle. For the problem that the DC bus voltage of the system is pulled down to affect the dynamic performance of the vehicle during rapid acceleration,the power balance control strategy of series hybrid tracked vehicle under the condition of rapid acceleration is studied. Based on the system fluctuation under different driving motor external characteristics,and the vehicle driving power demand and engine-generator response characteristics,a power balance control strategy for that engine-generator makes the voltage stable and DC/DC-battery provides the power compensation is proposed and verified by simulation. The results show that the strategy can balance the powers of the front and rear power chainsduring rapid acceleration,and the DC bus voltage fluctuation range is -4.6%-2.36%,which can maintain the system stability well.
