中文摘要

本文提出了一种基于磁链的直接模型预测电流控制(DMPC)方法,在稳态和瞬态运行下均表现出优异性能。该方法通过计算开关状态切换的最优时间点来实现控制,且无需依赖电机电感参数,从而增强了系统的鲁棒性。

English Abstract

This article presents a flux linkage-based direct model predictive current control approach that achieves favorable performance both during steady-state and transient operation. The former is achieved by computing the optimal time instants at which a new switch position is applied to the converter. To this end, the future current behavior is not computed based on the machine inductances or inducta...
