摘要

基于模型的预测控制是近年来提高功率变换器输出质量的一种新方法。在本研究中，预测电流控制在电压源逆变器中实现，工作在可变开关频率和固定开关频率下。实验结果验证了预测控制器的有效性，以及变频换相策略和定频换相策略的优点。总谐波失真(THD)的百分比和电流的绝对误差等值可以证明在固定频率下与经典控制相比策略的优越性。

Model Predictive Control in Three-Phase Inverters

Model-based predictive control is a recent alternative to improve the quality of the output in power converters. In this research, predictive current control is implemented in a voltage source inverter, operating at a variable switching frequency and at fixed switching frequency. Experimental results allowed to verify the effectiveness of the predictive controller, as well as the advantages of the commutation strategies at variable frequency and to fixed frequency. Values such as the percentage of total harmonic distortion (THD) and the absolute error of current allow to demonstrate the superiority of the strategies at fixed frequency in comparison with the classical control.
