Research on driving system of PMSM based on SVPWM control strategy

在详细研究空间矢量脉宽调制(Space Vector Pulse Width Modlulation,SVPWM)基本原理和实现方法的基础上,分析了永磁同步电机(Permanent Magnet Synchronous Motor,PMSM)的矢量控制策略,在Matlab/Simulink环境下建立基于SVPWM控制策略的转速和电流双闭环永磁同步电机调速系统仿真模型,并进行实验仿真;以英飞凌单片机XC2267为硬件驱动进行永磁同步电机SVPWM控制策略的实验验证,利用CAN总线分析仪对电机运行状态进行检测。仿真和实验结果表明了SVPWM控制策略在永磁同步电机驱动系统应用中的有效性,为相关电机控制系统的设计和调试提供了相应思路。

Based on details of the space vector pulse width modulation （SVPWM） and the realization of the basic principle of the method, the control strategy of permanent magnet synchronous motor （PMSM） is analyzed. A synchronous motor speed control system simulation model of SVPWM control strategy of speed and current double closed loop permanent magnet are built based on Matlab/ Simulink environment and experimental simulation. The Infineon XC2267 MCU is applied as hardware driver to carry out permanent magnet synchronous motor SVPWM control strategy experimental research. CAN Bus Analyzer is used to detect the running state of machine. The simulation and experimental results show that the SVPWM control strategy is effective on the permanent magnet synchronous motor driving system, which also provides thinking for design and debug of related motor control system.
