摘　　要：研究了预测电流控制四象限变流器的MATLAB建模与仿真方法,分析了变流器在牵引工况和再生制动工况时的特性。仿真和基于TMS320F2812试验样机的研究结果验证了该控制算法不仅能有效抑制注入电网的谐波电流,获得稳定的直流输出电压,实现了单位功率因数和能量双向流动,还具有良好的瞬态和稳态特性。A MATLAB simulation method was introduced to realize the predictive current control of 4 quadrant converter. Analysis of the dynamic response under traction condition and regeneration condition were performed. A prototype based on TMS320F2812 was built to verify the performance of the control scheme. Simulation and experiment results show that the harmonics are suppressed effectively and unity power factor can be achieved by using the control scheme. System has good dynamic and static characteristics.
