多相电机的多通道协调控制策略研究

Multi-channel harmonize control strategy research of multiphase motor

多相电机多通道变频驱动装置中变频驱动是几个独立单元,电机是一个整体,存在如何协调控制各个变频驱动通道,以保证不影响多相电机调速系统优点等问题,其协调控制策略研究具有重大价值。本文通过系统分析多相电机多通道控制存在问题,提出了一主多从的协调控制思想,并给出了具体协调措施;通过控制系统试验验证了该协调控制策略是有效的,在大功率变流器领域具有很好的应用前景。

The multi-channel converter device of multiphase motor include integral motor and some independent converters,The problem what harmonize every converter that assure not effective merits of multiphase motor speed regulating system is exist.The research of harmonize control strategy is important value.This paper analyse problem of multi-channel control base on multiphase motor,The harmonize control of one master and multi assistants and detailed harmonize control means are bringed forward,the well harmonize control effect of one master and multi assistants are proved by experiment,it has great applied foreground in high power converter domain.
