摘要:

针对永磁同步电机控制器存在算法复杂、代码量大、开发周期长等问题,实现一种基于虚拟仪器的永磁同步电机快速控制原型系统。设计快速控制原型硬件平台,并对硬件设备进行选型,包括PXI虚拟仪器、功率驱动模块、电机对拖台架等；研究永磁同步电机转子磁场定向控制原理基础上,以一台3.1KW被测电机为被控对象,在RT-LAB实时仿真软件环境下,搭建永磁同步电机控制算法模型。实验结果表明,电机转速与定子电流均可无偏差跟踪参考给定值,系统控制性能良好,且该系统使电机控制器开发周期缩短、成本降低。

Abstract:

To solve the problems of permanent magnet synchronous motor controller such as complex algorithm、large amount of code、long development cycle , this papaer puts forward a permanent magnet synchronous motor rapid control prototype system based on virtual instrument. Design the rapid control prototype hardware platform , and select the hardware device , which are PXI virtual instrument、power drive module、the motor test bench . Research on permanent magnet synchronous motor rotor field oriented control theory , with a 3.1 KW motor to be tested as the controlled object,in RT-LAB real-time simulation software environment,set up permanent magnet synchronous motor control algorithm model.The experimental results show that the rotor speed and stator current can be no deviation to track the reference set value , system control performance is good, and the system makes the motor controller to shorten the development cycle, lower cost.
