| 摘 要： | 模型预测控制(Model Predictive Control,MPC)是电压型逆变器(Voltage Source Inverter,VSI)电流跟随控制装置定频调制的典型方法,得到了广泛的应用。论文使用统计的方法研究MPC的采样时间与跟踪误差(方差)的函数关系。该函数关系是研究和解决逆变器切换优化问题的基础。仿真结果可得出采样时间与跟踪误差呈线性关系的结论。

| Abstract: | Model Predictive Control (MPC) is a typical method of voltage source inverter (VSI),which is widely used to control the constant frequency modulation.In this paper,we use statistical methods to study the function relationship between the sampling time of MPC and the tracking error (variance).The function relationship is the basis of research and solves the optimization problem of inverter switching.The simulation results show that the sampling time and tracking error are linear relationship. |

| Keywords: | error-sampling relationship model predictive control current following voltage source inverter |
