摘要
针对高频链矩阵变换器(HFLMC)易受不确定性因素干扰,导致输出功率波动的问题,提出一种动态矩阵控制器(DMC)优化控制方法.该方法采用预测控制方式,通过实时计算实际输出功率与预测输出功率的差值并产生控制量实现对网侧电流的控制.仿真结果表明,该方法在对复杂的耦合系统实施控制时,HFLMC的输出性能优良,相较于传统的PI控制器有更好的控制效果,系统的鲁棒性能更强.
Aiming at the problem that high frequency link matrix converter(HFLMC)is easy to be disturbed by uncertain factors,resulting in output power fluctuation,an optimal control method of dynamic matrix controller(DMC)is proposed in this paper.This method adopts the predictive control mode,calculates the difference between the actual output power and the predicted output power in real time,and generates the control quantity.The simulation results show that when the method is used to control the complex coupled system,the output performance of HFLMC is excellent,which has better control effect than the traditional PI controller,and enhances the robustness of the system.
