十八相电机模块化设计及改进的模型预测控制

Modular Design and Improved Model Predictive Control of 18-Phase Motor

以十八相电机为研究对象,通过电机的模块化设计对多相电机进行解耦,利用分层控制策略控制各个模块,引入底层基于触发条件的模型预测控制和顶层基于电压电流排序的控制算法,弥补了传统多相电机控制策略中运算量大、计算周期长、计算精度不高的缺点,提出了一种响应快、结构简单、计算量小的多相电机控制策略。

Eighteen-phase motor was the research object.Decoupled multi-phase motor through the modular design,used hierarchical control strategies to control each modules,and introduced model prediction control,which was based on trigger conditions at the bottom and voltage-current sequencing control at the top.The algorithm made up for the shortcomings of the traditional multiphase motor control strategy,such as large calculation amount,long calculation period,and low calculation accuracy.A multiphase motor control strategy with advantages of fast response,simple structure and less calculation amount was proposed.
