摘　　要：为提高电传动履带车辆电气系统稳定性,利用基于阻抗模型的小信号分析法对电传动履带车辆电力电子源网荷储所构建的直流微电网系统进行建模并结合电传动履带车辆工况条件开展分析,获取系统不同工况及不同参数变化下的稳定性规律和机理。在稳定性的理论分析基础上,分别在发动机-发电机组和DC/DC控制回路中设计基于电压的反馈通道和虚拟电容控制环节,所设计的控制环节能够自适应电压波动情况对电气系统进行控制,进而提升电传动履带车辆电气系统稳定性。通过仿真对控制算法进行了验证,证明了控制算法的有效性。In order to improve the stability of electric system of electric tracked vehicle,asmall signal analysis method based on impedance modelis used to model the DC microgrid system built by power electronic source network load and storage of electric tracked vehicle.Combined with the working conditions of electric tracked vehicle,the stability rule and mechanism of the system under different working conditions and different parameters are analyzed from the perspective of impedance matching.At the same time,in order to optimize and improve the stability of electric system for the electric tracked vehicle,a voltage-based feedback channel and a virtual capacitor control link are designed in the engine-generator set and DC/DC control loop,respectively.Thecontrol link can adapt to the voltage fluctuation for control,thus improving the stability of electric system in the electric tracked vehicle.Finally,the effectiveness and feasibility of the proposed method are verified by simulation.
