| 中文摘要:矿用电动轮车的电源由车载大功率柴油发电机组提供，容量有限，运行工况恶劣，负荷波动大，对动力系统运行稳定性和鲁棒性要求较高。用键合图对三相逆变器及LC滤波器进行建模，由键合图模型推导数学控制模型。将LC滤波器的一部分相当于电压源，对LC滤波的电容提供的电压进行控制，引入双向键合图，建立逆向键合图模型。针对三相LC滤波器的三相LC相当于电压源，LC为负载，设计谐振控制器。通过改变负载功率的大小而系统的极点的位置基本不发生变化来说明系统的稳定性问题，从而使变流系统达到复杂工况运行的鲁棒性要求。 |

| Abstract:Power supply capacity of truck provided by on-board high-power diesel generator is limited, poor operating conditions and wide load fluctuation demand more of system’s stability and robustness，Three phase inverter and LC filter are modeled by the bond graph where the mathematical control model is derived. Part of the LC filter is equivalent to the voltage source, and control the voltage of the capacitor in LC filter, the reverse bond graph model is established by introducing bi-way bond graph. View three-phase LC as voltage source, and LR load, design a resonant controller， and illustrate system stability by basically unchanged position of pole and zero during fluctuations in load， meeting its the end of robustness in complex operations. |
