摘　　要：在电机矢量控制系统中,由于受到控制器位数的限制,采用参数的有名值进行计算存在数据运算精度低、易溢出等问题。研究了永磁同步电机(PMSM)矢量控制系统参数标幺化的实现方案,推导了PMSM数学模型的标幺化方法和基本物理量基准值的选取,给出了采集信号标幺化的实现过程,最后基于TMS320F28335型数字信号处理器(DSP)进行了实验,实验验证了该方法的可行性、有效性。In the vector control system of the motor, because of the limited number of the controller, there are some disadvantages caused by using actual values for calculation, such as data overflow and low data precision.This paper focuses on the per-unit model realization of permanent magnet synchronous motor（PMSM） vector control.The method to get the per-unit model of PMSM is derived in detail.And the basic physical quantities and their base values are obtained.The process of transforming external signals into per-unit values is introduced.Finally ,some experiments axe done based on the feasibility of floating-point digital signal processing（DSP） TMS320F28335.The experimental results verify the validity and feasibility of the method.
