中文摘要

本文提出了一种针对永磁同步电机的有限控制集模型预测转矩控制(FCS-MPTC)动态优化策略。该策略同时考虑了逆变器损耗与电机损耗,通过引入约束条件优化开关序列,旨在有效降低逆变器开关损耗,提升驱动系统的整体效率。

English Abstract

This paper proposes a dynamic optimization strategy of finite control set-model predictive torque control for permanent magnet synchronous machines, which takes into account the inverter losses and machine losses simultaneously. In order to reduce the switching losses (or to optimize the switching sequence) of the inverter, a recognized and feasible constrain which considers the accumulated ON/OFF...
