| 摘 要： | 在异步电动机驱动的电动汽车运行过程中,驱动系统的直流侧电压和电流随着运行状态的不同而发生变化,从而会造成电动机控制性能的恶化.根据电动汽车驱动时直流侧电压需保持恒定,能量回馈时直流侧电流需保持恒定的要求,使用双向直流-直流变换器对直流侧电压和电流进行调整,正向工作时采用电压反馈并使用PI控制器镇定系统,反向工作时采用电流反馈并使用基于补偿环节的平均电流法镇定系统.分别建立了正向电压控制和反向电流控制的动态数学模型,利用输入电压和负载的阶跃扰动考验了系统的抗扰能力.通过MATLAB仿真证明了该控制方法的有效性和正确性.

| Abstract: | The voltage and current on the DC side of a EV driving system will change according to different running state of the EV.If they are not controlled properly,the driving system's performance will be getting worse.In this paper,a Bi-directional DC/DC converter is employed to achieve voltage stability in forward running state and current stability in backward running state based on the driving and regenerative braking requirements.In forward running state,voltage feedback with PI regulator added to the close l... |
