PMSM矢量控制调速系统建模与仿真 摘 要 随着科技更加便捷的发展，引进了一些新的更加方便，更加高效，更加准确，更加无损耗的技术，即PMSM矢量控制技术。第一，PMSM就是加入了新的材料，把之前的电动机做了改动，利用永磁材料替代之前的结构来维持电动机永恒的转动，使定子与转子的速度同步起来，这样的电动机就叫做永磁同步电机。直流励磁绕组相对于永磁材料来说损耗降低了。第二，矢量控制理论即就是通过控制电动机工作时的电流，主要是控制其中的磁场电流和转矩电流的角度大小和模值大小，把这种控制定子电流的方式称之为矢量控制。通过以上两种技术的改革，从而使对电动机的控制更加简洁，方便，高效。 本文的研究思路是先对永磁电动机的基本结构，工作原理，及其应用特点本做了简单的阐述，然后介绍了面装式电动机的矢量控制技术，最后建立永磁电动机的矢量控制调速系统，进行仿真数据，和最后的分析仿真结果。 关键词：PMSM矢量控制技术；永磁材料；矢量控制理论；建立；仿真 Abstract With the development of technology more convenient, the introduction of some new more convenient, more efficient, more accurate, more lossless technology, that is, PMSM vector control technology. First, PMSM is to add a new material, the previous motor to do the change, the use of permanent magnetic material to replace the previous structure to maintain the permanent rotation of the motor, so that the speed of the stator and the rotor together, this motor is called permanent magnet Synchronous motor. The DC field windings are reduced in loss relative to the permanent magnet material. Second, the vector control theory that is by controlling the motor current, mainly to control the magnetic field current and torque current angle size and modulus value, the way to control the stator current is called vector control. Through the reform of the above two technologies, so that the control of the motor more concise, convenient and efficient. This paper first studies the basic structure, working principle and application characteristics of the permanent magnet motor, and then introduces the vector control technology of the surface mount motor. Finally, the vector control speed of the permanent magnet motor is established. System, simulation data, and final analysis of simulation results. Key words：PMSM vector control technology; permanent magnet material; vector control theory; establishment; simulation １ 引言 随着二十一世纪科技的发展，永磁同步电动机（Permanent Magnet Synchronous Motor）的发展被广泛应用，电机研究成为社会使命中重要的研究课题之一[１]。电动机使用特别频繁，通以直流电流的电动机和通以交流电流的电动机在生活生产中都被应用的很广泛。电动机由于结构上做了改变
