摘　　要：针对传统FCS-MPC电流跟踪精度低的问题,提出一种能够快速准确实现电流跟踪控制的改进FCS-MPC方法。将代价函数中补偿电流转换为输出电压快速获取最优开关状态,通过三矢量代替单矢量减小补偿电流脉动,同时加入两步预测对电流跟踪控制进行时滞补偿。仿真结果表明,改进FCS-MPC的电流跟踪控制精度提高,APF谐波抑制性能更好。Aiming at the low accuracy of traditional FCS-MPC current tracking,an improved FCS-MPC method is proposed which can realize current tracking control quickly and accurately.The optimal switching state is quickly obtained by converting the compensated current into the output voltage in the cost function.The pulsation of the compensated current is reduced by replacing the single vector with three vectors.Meanwhile,the delay of current tracking control is compensated by adding double two-step prediction.The simulation results show that the improved FCS-MPC current tracking control precision is improved,and the APF harmonic suppression performan is better.
