  • 摘要: 提出了一种基于模型预测控制的矿山高压三电平ANPC变频器预测控制方案。该方案采用电流预测控制实现三电平有源中点钳位型高动态性能及单位功率因数控制,根据开关器件损耗选取与电压矢量唯一对应的开关状态。针对控制过程计算量大的问题,提出对系统进行延时补偿控制。仿真和实验结果表明,采用所提控制方案的三电平有源中点钳位型整流器动态响应快,具有良好的静、动态特性。

     

    Abstract: A predictive control program for mine high-pressure three-level ANPC inverter based on predictive model control was proposed. The program uses current predictive control to achieve three-level ANPC high dynamic performance and unity power factor control, selects switching state corresponding to voltage vector according to switching device loss. For problem of intensive calculated amount, delay compensation control was adopted. The simulation and experimental results show that three-level ANPC rectifier adopting the proposed control scheme has fast dynamic response, good static and dynamic characteristics.
