摘　　要：为充分利用电力电子半导体开关器件的离散特性构建控制集,将有限集模型预测控制应用于双向充电器,建立面向LCL滤波的预测模型,基于预测模型实现对下一控制周期电流的计算,构建代价函数实现矢量优选。通过仿真及试验测试双向充电器的稳态和动态性能,结果表明网侧电流正弦度高、响应快速,证实了该控制策略的正确性与可行性.To make full use of the discrete characteristics of electronic semiconductor switches to establish domination set,finite set model predictive was applied to bidirectional chargers.The predictive model of LCL filter was built up,and based on this model,current of the next control cycle can be calculated,and a cost function was built to achieve vector optimization.The steady-state and dynamic-state performance of the bidirectional charger were tested by simulation and experiment,which show that grid-side current features high sinusoidal output and fast response,verifying correctness and feasibility of the control strategy.
