摘要
针对永磁同步电机(PMSM)的矢量控制,基于图形化编程语言LabVIEW和虚拟仪器数据采集设备,编写实现了带有死区补偿的空间矢量脉宽调制(SVPWM)程序,产生了SVPWM信号,搭建了电机转速、电流等参数动态测量系统。在数字化交流PMSM调速系统上进行了验证,实验结果验证了利用虚拟仪器实现SVPWM方案的可行性,电机参数动态测量系统精度高、实时性强、响应速度快。
Based on the permanent magnet synchronous motor vector control（ PMSM）, programmed and realized space vector pulse width modulation（SVPWM） program with dead-time compensation based on the graphical programming language LabVIEW and virtual instrument data acquisition device, putted up motor speed and current dynamic measurement system. The SVPWM and dynamic measurement system were verified on the digital AC PMSM speed control system. The experimental results show that the scheme to use virtual instrument is feasible and the precision is high, the real-time is strong, and the response speed is quick in the motor dynamic measurement system.
