| 摘要: |
| 为解决DC/DC带给燃料电池汽车驱动系统成本及效率方面的问题,实现双电源之间的能量传输及对应转矩的独立控制,对双源电机驱动系统的工作模式、控制系统及输出性能进行分析。建立双源电机、燃料电池、动力电池模型,讨论双源电机的多种工作模式；针对双源电机两套绕组间的电压耦合效应,采用前馈解耦及零直轴电流策略对双源电机燃料电池绕组、动力电池绕组的电流及对应转矩进行独立控制；在实验室设计工况及基本市区循环试验工况下分别进行台架试验,双源电机驱动系统的输出转矩能够快速响应转矩需求,不同工作模式下燃料电池绕组及动力电池绕组的电流与其对应转矩波形一致。台架试验结果表明:双源电机驱动系统的多工作模式能够实现燃料电池汽车的启动、加速、下坡、制动能量回收等工况,所采用的控制策略可以对燃料电池及动力电池输出转矩进行独立控制,能够顺利实现燃料电池和动力电池之间的能量传输。 |

| Abstract: |
| The purpose of this paper is to tackle the problem of cost and efficiency brought by DC/DC to the fuel cell vehicle drive system. The energy transfer between dual power sources and the independent control of the corresponding torque are also expected to be realized. The operating mode, control system, and output performance of the dual-power source motor drive system were analyzed. Firstly, the models of the dual-power source electric motor, the fuel cell, and the power battery were developed. The multiple operating modes of the dual-power source electric motor were discussed. Then, considering the coupling effect between voltage of the two sets of windings in dual-power source motor, the feed-forward compensation combined zero direct-axis current strategy was adopted to control the winding current and corresponding torque individually. Finally, bench tests under laboratory-designed operating condition and basic urban drive cycle were conducted respectively. The output torque of the dual-power source electric motor drive system could quickly respond to the torque demand. The fuel cell and power battery winding currents in different operating modes were consistent with their corresponding torque waveforms. The bench test results showed that the multiple operating modes of the dual-power source electric motor drive system could realize the starting, acceleration, downhill, and braking energy recovery conditions of the fuel cell vehicle. The adopted control strategy could realize the independent control of the output torque corresponding to the fuel cell and power battery, and the energy transfer between the fuel cell and power battery. |
