单相缺相故障下双三相永磁同步电机矢量控制策略研究

Vector Control of DTPPMSM with Missing Phase

论文研究了单相缺相故障下不对称双三相永磁同步电机的矢量控制策略。从绕组解耦角度出发构造了虚拟等效的两相定子电流分量,提出了一种坐标变换的方法,有效地实现了不对称电机系统向对称电机系统的变换,实现了不对称三相电机的解耦控制问题,在控制上获得与直流他励电动机性能相似的结果。通过进行仿真,认为该策略使得双三相电机在运行的过程中电磁转矩脉动的问题能够有效减小,实现虚拟磁场定向解耦控制。

In this paper, single-phase phase vector asymmetric double fault phase permanent magnet synchronous motor control is studied Decoupled from winding angle construct virtual equivalent of two-phase stator current component a method of coordinate transformation is proposed, the transformation of asymmetric motor system to symmetrical motor system is achieved, the three phase asymmetry decoupling motor control problems are implemented effectively, him excited DC motor performance similar results are gotten in the control. Through simulation, that the policy making process in the two-phase motor running problem of electromagnetic torque ripple can be effectively reduced, virtual flux orientated decoupling control is realized.
